I'm trying to print certain line, from a string that is inside a variable in python3, the variable comes from os.popen execution like the following example.
some_url = os.popen(f"terraform state show 'module.dns.aws_route53_record.main'").read()
In order to print the output I do something like this
print(f"{color.DARKCYAN}[SOME_URL]{color.END}, {some_url}")
But the output look's like this...
[SOME_URL], # module.dns.aws_route53_record.main:
resource "aws_route53_record" "main" {
allow_overwrite = true
fqdn = "xxxxxxxxxx-xxxxxxxxxxxx-xxxxxxx-xxxxxx.xxxxxx.xxxxxxxx.xxxxxxx.com"
id = "xxxxxxxxxxxxxxxxxxxxxxxxx_xxxxx-xxxxxxxxxxxxx-xxxxxx-xxxxx.xxxxx.xxxx.xxxxxxx.com_CNAME"
name = "xxxxxxxxx-xxxxxxxxxxxxx-xxxxxxx-xxxxxxx.xxxxxxxxx.xx.xxxxxx.xxxx"
records = [
"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxx.xxxxxxxxxx.xxxx.xxxxxxxxxxxx.xxx",
]
ttl = xxxx
type = "xxxx"
zone_id = "xxxxxxxxxxxxxxxxxxxxxxxxxx"
}
Is it a simple way to parse and print just the line with the fqdn after [SOME_URL] ???
Is this what you were looking for?
import re
string = '''
resource "aws_route53_record" "main" {
allow_overwrite = true
fqdn = "xxxxxxxxxx-xxxxxxxxxxxx-xxxxxxx-xxxxxx.xxxxxx.xxxxxxxx.xxxxxxx.com"
id = "xxxxxxxxxxxxxxxxxxxxxxxxx_xxxxx-xxxxxxxxxxxxx-xxxxxx-xxxxx.xxxxx.xxxx.xxxxxxx.com_CNAME"
name = "xxxxxxxxx-xxxxxxxxxxxxx-xxxxxxx-xxxxxxx.xxxxxxxxx.xx.xxxxxx.xxxx"
records = [
"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxx.xxxxxxxxxx.xxxx.xxxxxxxxxxxx.xxx",
]
ttl = xxxx
type = "xxxx"
zone_id = "xxxxxxxxxxxxxxxxxxxxxxxxxx"
}
'''
if m := re.search("(?<=\n)\s*fqdn\s.*", string):
fqdn = re.sub("\s+=", " =", m.group().strip())
print(f"\x1b[1;36m[SOME_URL]\x1b[0m, {fqdn}")
[SOME_URL], fqdn = "xxxxxxxxxx-xxxxxxxxxxxx-xxxxxxx-xxxxxx.xxxxxx.xxxxxxxx.xxxxxxx.com"
The expression should be precise enough.
I can recommend learning regular expressions especially for these cases!
"Some people, when confronted with a problem, think 'I know, I'll use regular expressions.'
Now they have two problems."
"Regular expressions tend to be easier to write than they are to read. This is less of a problem if you are the only one who ever needs to maintain the program (or sed routine, or shell script, or what have you), but if several people need to watch over it, the syntax can turn into more of a hindrance than an aid.")
(Stephen Ramsay, University of Virginia)
Terraform has a very nice way to grant you access to information you need from the state in the form of outputs values. In your case, you can create an output variable for the fqdn and read just this one piece of information:
output "main_dns" {
value = aws_route53_record.main.fqdn
}
And in the python call you use the terraform output main_dns command
some_url = os.popen(f"terraform output main_dns").read()
Now you can use the fqdn as you see fit.

I have config file which contains network configurations something like given below.
LISTEN=192.168.180.1 #the network which listen the traffic
NETMASK=255.255.0.0
DOMAIN =test.com
Need to grep the values from the config. the following is my current code.
import re
with open('config.txt') as f:
data = f.read()
listen = re.findall('LISTEN=(.*)',data)
print listen
the variable listen contains
192.168.180.1 #the network which listen the traffic
but I no need the commented information but sometimes comments may not exist like other "NETMASK"
If you really want to this using regular expressions I would suggest changing it to LISTEN=([^#$]+)
Which should match anything up to the pound sign opening the comment or a newline character.
I come up with solution which will have common regex and replace "#".
import re
data = '''
LISTEN=192.168.180.1 #the network which listen the traffic
NETMASK=255.255.0.0
DOMAIN =test.com
'''
#Common regex to get all values
match = re.findall(r'.*=(.*)#*',data)
print "Total match found"
print match
#Remove # part if any
for index,val in enumerate(match):
if "#" in val:
val = (val.split("#")[0]).strip()
match[index] = val
print "Match after removing #"
print match
Output :
Total match found
['192.168.180.1 #the network which listen the traffic', '255.255.0.0', 'test.com']
Match after removing #
['192.168.180.1', '255.255.0.0', 'test.com']
data = """LISTEN=192.168.180.1 #the network which listen the traffic"""
import re
print(re.search(r'\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}', data).group())
>>>192.168.180.1
print(re.search(r'[0-9]+(?:\.[0-9]+){3}', data).group())
>>>192.168.180.1
In my experience regex is slow runtime and not very readable. I would do:
with open('config.txt') as f:
for line in f:
if not line.startswith("LISTEN="):
continue
rest = line.split("=", 1)[1]
nocomment = rest.split("#", 1)[0]
print nocomment
I think the better approach is to read the whole file as the format it is given in. I wrote a couple of tutorials, e.g. for YAML, CSV, JSON.
It looks as if this is an INI file.
Example Code
Example INI file
INI files need a header. I assume it is network:
[network]
LISTEN=192.168.180.1 #the network which listen the traffic
NETMASK=255.255.0.0
DOMAIN =test.com
Python 2
#!/usr/bin/env python
import ConfigParser
import io
# Load the configuration file
with open("config.ini") as f:
sample_config = f.read()
config = ConfigParser.RawConfigParser(allow_no_value=True)
config.readfp(io.BytesIO(sample_config))
# List all contents
print("List all contents")
for section in config.sections():
print("Section: %s" % section)
for options in config.options(section):
print("x %s:::%s:::%s" % (options,
config.get(section, options),
str(type(options))))
# Print some contents
print("\nPrint some contents")
print(config.get('other', 'use_anonymous')) # Just get the value
Python 3
Look at configparser:
#!/usr/bin/env python
import configparser
# Load the configuration file
config = configparser.RawConfigParser(allow_no_value=True)
with open("config.ini") as f:
config.readfp(f)
# Print some contents
print(config.get('network', 'LISTEN'))
gives:
192.168.180.1 #the network which listen the traffic
Hence you need to parse that value as well, as INI seems not to know #-comments.
I have this string "IP 1.2.3.4 is currently trusted in the white list, but it is now using a new trusted certificate." in a log file. What I need to do is look for this message and extract the IP address (1.2.3.4) from the log file.
import os
import shutil
import optparse
import sys
def main():
file = open("messages", "r")
log_data = file.read()
file.close()
search_str = "is currently trusted in the white list, but it is now using a new trusted certificate."
index = log_data.find(search_str)
print index
return
if __name__ == '__main__':
main()
How do I extract the IP address? Your response is appreciated.
Really simple answer:
msg = "IP 1.2.3.4 is currently trusted in the white list, but it is now using a new trusted certificate."
parts = msg.split(' ', 2)
print parts[1]
results in:
1.2.3.4
You could also do REs if you wanted, but for something this simple...
There will be dozens of possible approaches, pros and cons depend on the details of your log file. One example, using the re module:
import re
x = "IP 1.2.3.4 is currently trusted in the white list, but it is now using a new trusted certificate."
pattern = "IP ([0-9\.]+) is currently trusted in the white list"
m = re.match(pattern, x)
for ip in m.groups():
print ip
If you want to print out every instance of that string in your log file, you'd do something like this:
import re
pattern = "(IP [9-0\.]+ is currently trusted in the white list, but it is now using a new trusted certificate.)"
m = re.match(pattern, log_data)
for match in m.groups():
print match
Use regular expressions.
Code like this:
import re
compiled = re.compile(r"""
.*? # Leading junk
(?P<ipaddress>\d+\.\d+\.\d+\.\d+) # IP address
.*? # Trailing junk
""", re.VERBOSE)
str = "IP 1.2.3.4 is currently trusted in the white list, but it is now using a new trusted certificate."
m = compiled.match(str)
print m.group("ipaddress")
And you get this:
>>> import re
>>>
>>> compiled = re.compile(r"""
... .*? # Leading junk
... (?P<ipaddress>\d+\.\d+\.\d+\.\d+) # IP address
... .*? # Trailing junk
... """, re.VERBOSE)
>>> str = "IP 1.2.3.4 is currently trusted in the white list, but it is now using a new trusted certificate."
>>> m = compiled.match(str)
>>> print m.group("ipaddress")
1.2.3.4
Also, I learned there there is a dictionary of matches, groupdict():
>>>> str = "Peer 10.11.6.224 is currently trusted in the white list, but it is now using a new trusted certificate. Consider removing its likely outdated white list entry."
>>>> m = compiled.match(str)
>>>> print m.groupdict()
{'ipaddress': '10.11.6.224'}
Later: fixed that. The initial '.*' was eating your first character match. Changed it to be non-greedy. For consistency (but not necessity), I changed the trailing match, too.
Regular expression is the way to go. But if you fill uncomfortably writing them, you can try a small parser that I wrote (https://github.com/hgrecco/stringparser). It translates a string format to a regular expression. In your case, you will do the following:
from stringparser import Parser
parser = Parser("IP {} is currently trusted in the white list, but it is now using a new trusted certificate.")
ip = parser(text)
If you have a file with multiple lines you can replace the last line by:
with open("log.txt", "r") as fp:
ips = [parser(line) for line in fp]
Good luck.
Given the following format (.properties or .ini):
propertyName1=propertyValue1
propertyName2=propertyValue2
...
propertyNameN=propertyValueN
For Java there is the Properties class that offers functionality to parse / interact with the above format.
Is there something similar in python's standard library (2.x) ?
If not, what other alternatives do I have ?
I was able to get this to work with ConfigParser, no one showed any examples on how to do this, so here is a simple python reader of a property file and example of the property file. Note that the extension is still .properties, but I had to add a section header similar to what you see in .ini files... a bit of a bastardization, but it works.
The python file: PythonPropertyReader.py
#!/usr/bin/python
import ConfigParser
config = ConfigParser.RawConfigParser()
config.read('ConfigFile.properties')
print config.get('DatabaseSection', 'database.dbname');
The property file: ConfigFile.properties
[DatabaseSection]
database.dbname=unitTest
database.user=root
database.password=
For more functionality, read: https://docs.python.org/2/library/configparser.html
For .ini files there is the configparser module that provides a format compatible with .ini files.
Anyway there's nothing available for parsing complete .properties files, when I have to do that I simply use jython (I'm talking about scripting).
I know that this is a very old question, but I need it just now and I decided to implement my own solution, a pure python solution, that covers most uses cases (not all):
def load_properties(filepath, sep='=', comment_char='#'):
"""
Read the file passed as parameter as a properties file.
"""
props = {}
with open(filepath, "rt") as f:
for line in f:
l = line.strip()
if l and not l.startswith(comment_char):
key_value = l.split(sep)
key = key_value[0].strip()
value = sep.join(key_value[1:]).strip().strip('"')
props[key] = value
return props
You can change the sep to ':' to parse files with format:
key : value
The code parses correctly lines like:
url = "http://my-host.com"
name = Paul = Pablo
# This comment line will be ignored
You'll get a dict with:
{"url": "http://my-host.com", "name": "Paul = Pablo" }
A java properties file is often valid python code as well. You could rename your myconfig.properties file to myconfig.py. Then just import your file, like this
import myconfig
and access the properties directly
print myconfig.propertyName1
if you don't have multi line properties and a very simple need, a few lines of code can solve it for you:
File t.properties:
a=b
c=d
e=f
Python code:
with open("t.properties") as f:
l = [line.split("=") for line in f.readlines()]
d = {key.strip(): value.strip() for key, value in l}
If you have an option of file formats I suggest using .ini and Python's ConfigParser as mentioned. If you need compatibility with Java .properties files I have written a library for it called jprops. We were using pyjavaproperties, but after encountering various limitations I ended up implementing my own. It has full support for the .properties format, including unicode support and better support for escape sequences. Jprops can also parse any file-like object while pyjavaproperties only works with real files on disk.
This is not exactly properties but Python does have a nice library for parsing configuration files. Also see this recipe: A python replacement for java.util.Properties.
i have used this, this library is very useful
from pyjavaproperties import Properties
p = Properties()
p.load(open('test.properties'))
p.list()
print(p)
print(p.items())
print(p['name3'])
p['name3'] = 'changed = value'
Here is link to my project: https://sourceforge.net/projects/pyproperties/. It is a library with methods for working with *.properties files for Python 3.x.
But it is not based on java.util.Properties
This is a one-to-one replacement of java.util.Propeties
From the doc:
def __parse(self, lines):
""" Parse a list of lines and create
an internal property dictionary """
# Every line in the file must consist of either a comment
# or a key-value pair. A key-value pair is a line consisting
# of a key which is a combination of non-white space characters
# The separator character between key-value pairs is a '=',
# ':' or a whitespace character not including the newline.
# If the '=' or ':' characters are found, in the line, even
# keys containing whitespace chars are allowed.
# A line with only a key according to the rules above is also
# fine. In such case, the value is considered as the empty string.
# In order to include characters '=' or ':' in a key or value,
# they have to be properly escaped using the backslash character.
# Some examples of valid key-value pairs:
#
# key value
# key=value
# key:value
# key value1,value2,value3
# key value1,value2,value3 \
# value4, value5
# key
# This key= this value
# key = value1 value2 value3
# Any line that starts with a '#' is considerered a comment
# and skipped. Also any trailing or preceding whitespaces
# are removed from the key/value.
# This is a line parser. It parses the
# contents like by line.
You can use a file-like object in ConfigParser.RawConfigParser.readfp defined here -> https://docs.python.org/2/library/configparser.html#ConfigParser.RawConfigParser.readfp
Define a class that overrides readline that adds a section name before the actual contents of your properties file.
I've packaged it into the class that returns a dict of all the properties defined.
import ConfigParser
class PropertiesReader(object):
def __init__(self, properties_file_name):
self.name = properties_file_name
self.main_section = 'main'
# Add dummy section on top
self.lines = [ '[%s]\n' % self.main_section ]
with open(properties_file_name) as f:
self.lines.extend(f.readlines())
# This makes sure that iterator in readfp stops
self.lines.append('')
def readline(self):
return self.lines.pop(0)
def read_properties(self):
config = ConfigParser.RawConfigParser()
# Without next line the property names will be lowercased
config.optionxform = str
config.readfp(self)
return dict(config.items(self.main_section))
if __name__ == '__main__':
print PropertiesReader('/path/to/file.properties').read_properties()
If you need to read all values from a section in properties file in a simple manner:
Your config.properties file layout :
[SECTION_NAME]
key1 = value1
key2 = value2
You code:
import configparser
config = configparser.RawConfigParser()
config.read('path_to_config.properties file')
details_dict = dict(config.items('SECTION_NAME'))
This will give you a dictionary where keys are same as in config file and their corresponding values.
details_dict is :
{'key1':'value1', 'key2':'value2'}
Now to get key1's value :
details_dict['key1']
Putting it all in a method which reads that section from config file only once(the first time the method is called during a program run).
def get_config_dict():
if not hasattr(get_config_dict, 'config_dict'):
get_config_dict.config_dict = dict(config.items('SECTION_NAME'))
return get_config_dict.config_dict
Now call the above function and get the required key's value :
config_details = get_config_dict()
key_1_value = config_details['key1']
-------------------------------------------------------------
Extending the approach mentioned above, reading section by section automatically and then accessing by section name followed by key name.
def get_config_section():
if not hasattr(get_config_section, 'section_dict'):
get_config_section.section_dict = dict()
for section in config.sections():
get_config_section.section_dict[section] =
dict(config.items(section))
return get_config_section.section_dict
To access:
config_dict = get_config_section()
port = config_dict['DB']['port']
(here 'DB' is a section name in config file
and 'port' is a key under section 'DB'.)
create a dictionary in your python module and store everything into it and access it, for example:
dict = {
'portalPath' : 'www.xyx.com',
'elementID': 'submit'}
Now to access it you can simply do:
submitButton = driver.find_element_by_id(dict['elementID'])
My Java ini files didn't have section headers and I wanted a dict as a result. So i simply injected an "[ini]" section and let the default config library do its job.
Take a version.ini fie of the eclipse IDE .metadata directory as an example:
#Mon Dec 20 07:35:29 CET 2021
org.eclipse.core.runtime=2
org.eclipse.platform=4.19.0.v20210303-1800
# 'injected' ini section
[ini]
#Mon Dec 20 07:35:29 CET 2021
org.eclipse.core.runtime=2
org.eclipse.platform=4.19.0.v20210303-1800
The result is converted to a dict:
from configparser import ConfigParser
#staticmethod
def readPropertyFile(path):
# https://stackoverflow.com/questions/3595363/properties-file-in-python-similar-to-java-properties
config = ConfigParser()
s_config= open(path, 'r').read()
s_config="[ini]\n%s" % s_config
# https://stackoverflow.com/a/36841741/1497139
config.read_string(s_config)
items=config.items('ini')
itemDict={}
for key,value in items:
itemDict[key]=value
return itemDict
This is what I'm doing in my project: I just create another .py file called properties.py which includes all common variables/properties I used in the project, and in any file need to refer to these variables, put
from properties import *(or anything you need)
Used this method to keep svn peace when I was changing dev locations frequently and some common variables were quite relative to local environment. Works fine for me but not sure this method would be suggested for formal dev environment etc.
import json
f=open('test.json')
x=json.load(f)
f.close()
print(x)
Contents of test.json:
{"host": "127.0.0.1", "user": "jms"}
I have created a python module that is almost similar to the Properties class of Java ( Actually it is like the PropertyPlaceholderConfigurer in spring which lets you use ${variable-reference} to refer to already defined property )
EDIT : You may install this package by running the command(currently tested for python 3).
pip install property
The project is hosted on GitHub
Example : ( Detailed documentation can be found here )
Let's say you have the following properties defined in my_file.properties file
foo = I am awesome
bar = ${chocolate}-bar
chocolate = fudge
Code to load the above properties
from properties.p import Property
prop = Property()
# Simply load it into a dictionary
dic_prop = prop.load_property_files('my_file.properties')
Below 2 lines of code shows how to use Python List Comprehension to load 'java style' property file.
split_properties=[line.split("=") for line in open('/<path_to_property_file>)]
properties={key: value for key,value in split_properties }
Please have a look at below post for details
https://ilearnonlinesite.wordpress.com/2017/07/24/reading-property-file-in-python-using-comprehension-and-generators/
you can use parameter "fromfile_prefix_chars" with argparse to read from config file as below---
temp.py
parser = argparse.ArgumentParser(fromfile_prefix_chars='#')
parser.add_argument('--a')
parser.add_argument('--b')
args = parser.parse_args()
print(args.a)
print(args.b)
config file
--a
hello
--b
hello dear
Run command
python temp.py "#config"
You could use - https://pypi.org/project/property/
eg - my_file.properties
foo = I am awesome
bar = ${chocolate}-bar
chocolate = fudge
long = a very long property that is described in the property file which takes up \
multiple lines can be defined by the escape character as it is done here
url=example.com/api?auth_token=xyz
user_dir=${HOME}/test
unresolved = ${HOME}/files/${id}/${bar}/
fname_template = /opt/myapp/{arch}/ext/{objid}.dat
Code
from properties.p import Property
## set use_env to evaluate properties from shell / os environment
prop = Property(use_env = True)
dic_prop = prop.load_property_files('my_file.properties')
## Read multiple files
## dic_prop = prop.load_property_files('file1', 'file2')
print(dic_prop)
# Output
# {'foo': 'I am awesome', 'bar': 'fudge-bar', 'chocolate': 'fudge',
# 'long': 'a very long property that is described in the property file which takes up multiple lines
# can be defined by the escape character as it is done here', 'url': 'example.com/api?auth_token=xyz',
# 'user_dir': '/home/user/test',
# 'unresolved': '/home/user/files/${id}/fudge-bar/',
# 'fname_template': '/opt/myapp/{arch}/ext/{objid}.dat'}
I did this using ConfigParser as follows. The code assumes that there is a file called config.prop in the same directory where BaseTest is placed:
config.prop
[CredentialSection]
app.name=MyAppName
BaseTest.py:
import unittest
import ConfigParser
class BaseTest(unittest.TestCase):
def setUp(self):
__SECTION = 'CredentialSection'
config = ConfigParser.ConfigParser()
config.readfp(open('config.prop'))
self.__app_name = config.get(__SECTION, 'app.name')
def test1(self):
print self.__app_name % This should print: MyAppName
This is what i had written to parse file and set it as env variables which skips comments and non key value lines added switches to specify
hg:d
-h or --help print usage summary
-c Specify char that identifies comment
-s Separator between key and value in prop file
and specify properties file that needs to be parsed eg : python
EnvParamSet.py -c # -s = env.properties
import pipes
import sys , getopt
import os.path
class Parsing :
def __init__(self , seprator , commentChar , propFile):
self.seprator = seprator
self.commentChar = commentChar
self.propFile = propFile
def parseProp(self):
prop = open(self.propFile,'rU')
for line in prop :
if line.startswith(self.commentChar)==False and line.find(self.seprator) != -1 :
keyValue = line.split(self.seprator)
key = keyValue[0].strip()
value = keyValue[1].strip()
print("export %s=%s" % (str (key),pipes.quote(str(value))))
class EnvParamSet:
def main (argv):
seprator = '='
comment = '#'
if len(argv) is 0:
print "Please Specify properties file to be parsed "
sys.exit()
propFile=argv[-1]
try :
opts, args = getopt.getopt(argv, "hs:c:f:", ["help", "seprator=","comment=", "file="])
except getopt.GetoptError,e:
print str(e)
print " possible arguments -s <key value sperator > -c < comment char > <file> \n Try -h or --help "
sys.exit(2)
if os.path.isfile(args[0])==False:
print "File doesnt exist "
sys.exit()
for opt , arg in opts :
if opt in ("-h" , "--help"):
print " hg:d \n -h or --help print usage summary \n -c Specify char that idetifes comment \n -s Sperator between key and value in prop file \n specify file "
sys.exit()
elif opt in ("-s" , "--seprator"):
seprator = arg
elif opt in ("-c" , "--comment"):
comment = arg
p = Parsing( seprator, comment , propFile)
p.parseProp()
if __name__ == "__main__":
main(sys.argv[1:])
Lightbend has released the Typesafe Config library, which parses properties files and also some JSON-based extensions. Lightbend's library is only for the JVM, but it seems to be widely adopted and there are now ports in many languages, including Python: https://github.com/chimpler/pyhocon
You can use the following function, which is the modified code of #mvallebr. It respects the properties file comments, ignores empty new lines, and allows retrieving a single key value.
def getProperties(propertiesFile ="/home/memin/.config/customMemin/conf.properties", key=''):
"""
Reads a .properties file and returns the key value pairs as dictionary.
if key value is specified, then it will return its value alone.
"""
with open(propertiesFile) as f:
l = [line.strip().split("=") for line in f.readlines() if not line.startswith('#') and line.strip()]
d = {key.strip(): value.strip() for key, value in l}
if key:
return d[key]
else:
return d
this works for me.
from pyjavaproperties import Properties
p = Properties()
p.load(open('test.properties'))
p.list()
print p
print p.items()
print p['name3']
I followed configparser approach and it worked quite well for me. Created one PropertyReader file and used config parser there to ready property to corresponding to each section.
**Used Python 2.7
Content of PropertyReader.py file:

strValue = config.get(strSection,strKey);
print "Value captured for "+strKey+" :"+strValue
return strValue
Content of read schema file:

You can try the python-dotenv library. This library reads key-value pairs from a .env (so not exactly a .properties file though) file and can set them as environment variables.
Here's a sample usage from the official documentation:
from dotenv import load_dotenv
load_dotenv() # take environment variables from .env.
# Code of your application, which uses environment variables (e.g. from `os.environ` or
# `os.getenv`) as if they came from the actual environment.
