Cannot import python class from another folder

I have created 2 classes
Connections.py and LogObserver.py
I am trying to import Connections.py in LogObserver.py but python keep throwing an error
ModuleNotFoundError: No module named 'connections'
The way i am importing it is
from connections.Connections import Connections
class LogObserver:
The file structure is

If your Class name in Connections file is called Connections then you can try following:
from connections import Connections
c = Connections.Connections()
Or:
import connections.Connections as myModule
c = myModule.Connections()
make sure when you import that you do following:
from <folder>.<filename> import <class_name>

There is a problem in your file structure.
Try keeping connections folder inside queries folder OR specify the file path for connections.py correctly.
Hope it resolves the issue.

How to load environment variables in a config.ini file?

I have a config.ini file which contains some properties but I want to read the environment variables inside the config file.
[section1]
prop1:(from envrinment variable) or value1
Is this possible or do I have to write a method to take care of that?

I know this is late to the party, but someone might find this handy.
What you are asking after is value interpolation combined with os.environ.
Pyramid?
The logic of doing so is unusual and generally this happens if one has a pyramid server, (which is read by a config file out of the box) while wanting to imitate a django one (which is always set up to read os.environ).
If you are using pyramid, then pyramid.paster.get_app has the argument options: if you pass os.environ as the dictionary you can use %(variable)s in the ini. Not that this is not specific to pyramid.paster.get_app as the next section shows (but my guess is get_app is the case).
app.py
from pyramid.paster import get_app
from waitress import serve
import os
app = get_app('production.ini', 'main', options=os.environ)
serve(app, host='0.0.0.0', port=8000, threads=50)
production.ini:
[app:main]
sqlalchemy.url = %(SQL_URL)s
...
Configparse?
The above is using configparser basic interpolation.
Say I have a file called config.ini with the line
[System]
conda_location = %(CONDA_PYTHON_EXE)
The following will work...
import configparser, os
cfg = configparser.ConfigParser()
cfg.read('config.ini')
print(cfg.get('System', 'conda_location', vars=os.environ))

I think :thinking_face, use .env and in config.py from dotenv import load_dotenv() and in next line load_dotenv() and it will load envs from .env file

sys.path.append causing 500 error in Flask

I have a flask app that is giving me 500 when I import a file using sys.path.append('path/to/file.py)
Here is my file located in /var/www/html/ip.py which flask is calling:
import sys
sys.path.append('/auto/conf/')
from config import config
server_username = config['server_username']
server_password = config['server_prod_password']
def check_ip(ip_addr):
return "test"
Here is my /auto/conf/config.py:
import os
import ConfigParser
# Define names of dir and file
CRED_DIR = 'cred'
FILE_NAME = 'cred.conf'
# Path to cred file
my_dir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
cred_dir = os.path.join(my_dir, CRED_DIR)
file_path = os.path.join(cred_dir, FILE_NAME)
# Load the conf file with ConfigParser
config = ConfigParser.SafeConfigParser()
config.read(file_path)
# Build a config dictionary
config = {
'server_username': config.get('server', 'username'),
'server_password': config.get('server', 'password'),
}
and cred.conf is located in /auto/cred/cred.conf and contains server info.
Now, here is the issue. If I run python ip.py, it runs fine. I added print statement and it was fetching proper server username and password. But when I run it via Flask, it gives me 500 error.
Here are some of the things I tried:
-- If I comment out "from config import config" from ip.py, Flask runs returns "test" meaning it worked. It will not get server un and pw but atleast it does not 500.
-- If I move cred.conf and config.py to same directory as ip.py and comment out "sys.path.append('/auto/conf/')" and uncomment "from config import config", Flask works.
Any ideas why its happening? I am thinking Flask does not like sys.path.append. Is there any alternative I can use so Flask works?
Edit:
I changed ip.py to this:
import sys
sys.path.append('/auto/conf/')
import config
and removed all code in config.py and it is still gving me error. If I comment out "import config", Flask works. Definitely it does not like importing in this fashion..

How to get config params in another module in flask python?

In my main.py have the below code:
app.config.from_object('config.DevelopmentConfig')
In another module I used import main and then used main.app.config['KEY'] to get a parameter, but Python interpreter says that it couldn't load the module in main.py because of the import part. How can I access config parameters in another module in Flask?

Your structure is not really clear but by what I can get, import your configuration object and just pass it to app.config.from_object():
from flask import Flask
from <path_to_config_module>.config import DevelopmentConfig
app = Flask('Project')
app.config.from_object(DevelopmentConfig)
if __name__ == "__main__":
application.run(host="0.0.0.0")
if your your config module is in the same directory where your application module is, you can just use :
from .config import DevelopmentConfig

The solution was to put app initialization in another file (e.g: myapp_init_file.py) in the root:
from flask import Flask
app = Flask(__name__)
# Change this on production environment to: config.ProductionConfig
app.config.from_object('config.DevelopmentConfig')
Now to access config parameters I just need to import this module in different files:
from myapp_init_file import app
Now I have access to my config parameters as below:
app.config['url']
The problem was that I had an import loop an could not run my python app. With this solution everything works like a charm. ;-)

importing error in python while importing two classes

I am working with a python script, and i face importing problem when i try to import a class from another python script. Here is how my python project folder looks:
Mysql_Main/
checks.py
Analyzer/
config.py
ip.py
op.py
__init__.py
Now i want to import two classes named: Config() and Sqlite() from config.py into the checks.py script.How do i do it?
This is what i tried, but its resulting in an error!
inside checks.py:
from Analyzer import config
config = config.Config()
sqlite = config.Sqlite()
The problem is that Config class is imported properly, but Sqlite class is not getting imported.It is showing error - Config instance has no attribute 'Sqlite'

When you do:
config = config.Config()
You write over the variable config and it no longer points to the module config. It stores the new Config instance.
Try:
from Analyzer import config
config_instance = config.Config()
sqlite_instance = config.Sqlite()
