The \n just doesn't seem to work for me when I use it with print. I am using Python 2.7.8. I don't get whats wrong, I think \n with a print should print a new line very straight forwardly.
import sys
import os
import subprocess
from collections import OrderedDict
import xmlrpclib
import hawkey
op_name = sys.argv[1]
pkg_name = sys.argv[2]
# Hawkey Configurations
sack = hawkey.Sack()
path = "/home/thejdeep/test_repo/repodata/%s"
repo = hawkey.Repo("test")
repo.repomd_fn = path % "repomd.xml"
repo.primary_fn = path % "b6f6911f7d9fb63f001388f1ecd0766cec060c1d04c703c6a74969eadc24ec97-primary.xml.gz"
repo.filelists_fn = path % "df5897ed6d3f87f2be4432543edf2f58996e5c9e6a7acee054f9dbfe513df4da-filelists.xml.gz"
sack.load_repo(repo,load_filelists=True)
# Main Function
if __name__ == "__main__":
print "Querying the repository\n"
print "-----------------------\n"
print "Found packages :\n"
print "--------------\n"
q = hawkey.Query(sack)
q = q.filter(name=pkg_name,latest_per_arch=True)[0]
if q:
for pkg in q:
print str(pkg)
else:
print "No packages with name "+pkg_name+" found. Exiting"
sys.exit()
print "--------------------"
print "Performing Dependency Check"
Output is something like this. Basically its printing in the same line :
Querying the repository ----------------------- Found packages : --------------
Using print method automatically add \n at the end of the line so its not necessary put \n at the end of each line.

Please let me know how can i pass the runtime input i am taking for my delete function as an argument like others.
I an new to python and experimenting with the language
When I run then i get error.why print man gave error and also os.getwd() also give error.But when i comment that then there is no error.code works according to expectation
from __future__ import print_function;
import os
man=[]
other = []
print os.getcwd()
try:
data = open("sketch.txt")
for each_line in data:
try:
(role,line_spoken) = each_line.split(':',1)
line_spoken = line_spoken.strip()
if role=='Man':
man.append(line_spoken)
elif role =='Other Man':
other.append(line_spoken)
except ValueError:
pass
data.close()
except IOError:
print ("The Data File is Missing")
print man
print other
try:
man_file = open('man_data.txt','w')
other_file = open('other_data.txt','w')
print (man,file = man_file)
print (other,file = other_file)
other_file.close()
man_file.close()
except IOError:
pass
You should call print as function, because you import print_function:
from __future__ import print_function
print("Hello World")
As far as I see the following.
1) In the first line there is a ';' that could be removed.
2) the second line 'import...' and the rest to the bottom have tabs that should be removed. These lines should be in the same col that line 1 ('from ...')
3) when you use 'print' (as other people are saying) you should use '(' & ')'.
4) for coherence you should get used to follow the same approach in all your code (good practiceS), if there are no spaces between function names and parameters (i.e. line 7: data = open("sketch...) then go on with them. The same for strings, the code compile, but it is better if you use ' or " not mix them along the code.
looking forward to help!
I am trying to learn Python, and thought I'd learn by writing something I'd actually use. SO I'm trying to write a little script to rip some music CDs.
I am using the musicbrainzngs package. I would like to get the tracklist of the CD. My code currently:
#! /usr/bin/env python
import argparse
import musicbrainzngs
import discid
musicbrainzngs.set_useragent("Audacious", "0.1", "https://github.com/jonnybarnes/audacious")
parser = argparse.ArgumentParser()
parser.add_argument("--cdrom", help="provide the source of the cd", default="/dev/cdrom")
args = parser.parse_args()
device = args.cdrom
print("device: %s" % device)
disc = discid.read(device)
print("id: %s" % disc.id)
try:
result = musicbrainzngs.get_releases_by_discid(disc.id, includes=["artists"])
except musicbrainzngs.ResponseError:
print("disc not found or bad response")
else:
if result.get("disc"):
print("artist:\t%s" %
result["disc"]["release-list"][0]["artist-credit-phrase"])
print("title:\t%s" % result["disc"]["release-list"][0]["title"])
elif result.get("cdstub"):
print("artist:\t" % result["cdstub"]["artist"])
print("title:\t" % result["cdstub"]["title"])
How can I get the tracklist, looking at the full results returned there is a track-list property but regardless of what CD I try the result is always empty
Getting releases by discid is a lookup and its "'inc=' arguments supported are identical to a lookup request for a release" which are listed earlier on that page. To get a non-empty tracklist you simply need to add the "recordings" include:
result = musicbrainzngs.get_releases_by_discid(disc.id, includes=["artists", "recordings"])
This is an example script for getting the tracklist for an album using musicbrainzngs
#!/usr/bin/python3
from __future__ import print_function
from __future__ import unicode_literals
import musicbrainzngs
import sys
musicbrainzngs.set_useragent(
"python-musicbrainzngs-example",
"0.1",
"https://github.com/alastair/python-musicbrainzngs/",
)
def get_tracklist(artist, album):
result = musicbrainzngs.search_releases(artist=artist, release=album, limit=1)
id = result["release-list"][0]["id"]
#### get tracklist
new_result = musicbrainzngs.get_release_by_id(id, includes=["recordings"])
t = (new_result["release"]["medium-list"][0]["track-list"])
for x in range(len(t)):
line = (t[x])
print(f'{line["number"]}. {line["recording"]["title"]}')
if __name__ == '__main__':
### get first release
if len(sys.argv) > 1:
artist, album = [sys.argv[1], sys.argv[2]]
get_tracklist(artist, album)
else:
artist = input("Artist: ")
album = input("Album: ")
if not artist == "" and not album == "":
get_tracklist(artist, album)
else:
print("Artist or Album missing")
Usage:
python3 album_get_tracklist.py "rolling stones" "beggars banquet"
or
python3 album_get_tracklist.py
it will ask for Artist and Album
I'm trying to compare a csv file containing required Linux packages with the current installed packages. The comparison should output any packages not installed or newer than the current installed packages.
The problem is that I'm unable to loop through the list of installed packages and show all hits, for instance packages with the same name and version, but different architecture should be shown twice(for instance compat-libstdc++-33), but I only getting the first hit with the script below.
#!/usr/bin/python
import rpm

atk,1.12.2

libusb,0.1.12
libfontenc,1.4.2

print ''
sys.exit(1)
else:
input_csv = sys.argv[1]
pkgRequired = csv.reader(open(input_csv),delimiter=',')
pkgInstalledName = []
pkgInstalledVersion = []
pkgInstalledArch = []
ts = rpm.TransactionSet()
mi = ts.dbMatch()
for h in mi:
pkgInstalledName.append((h['name']))
pkgInstalledVersion.append((h['version']))
pkgInstalledArch.append((h['arch']))
for row in pkgRequired:
pkgRequiredName = row[0]
pkgRequiredVersion = row[1]
#pkgRequiredArch = row[2]
if pkgRequiredName in pkgInstalledName:
if pkgInstalledVersion[pkgInstalledName.index(pkgRequiredName)] >= pkgRequiredVersion:
pass
else:
print '\nInstalled: ',pkgInstalledName[pkgInstalledName.index(pkgRequiredName)], pkgInstalledVersion[pkgInstalledName.index(pkgRequiredName)], pkgInstalledArch[pkgInstalledName.index(pkgRequiredName)], ' \nRequired: ', ' ', pkgRequiredName,pkgRequiredVersion
Assuming that there's no problem with the way that you're reading the list of installed packages (I'm not familiar with the rpm module), then your only problem is with using the index() function. This function return the first occurrence of an item with the specified value - and it isn't what you want.
A correct implementation (which is also much more efficient) would be:
installedPackages = {} #create a hash table, mapping package names to LISTS of installed package versions and architectures
for h in mi:
l = installedPackages.get(h['name'], list()) #return either the existing list, or a new one if this is the first time that the name appears.
l.append( (h['version'], h['arch']) )
...
if requiredPackageName in installedPackages:
for ver, arch in installedPackages[requiredPackageName]: print ...
This is what I ended up doing to get this working. The script currently is not checking for the architecture of required packages, but at least it shows the arch installed. The script works (as far as I know) but can be improved as its my first at python :)

Running the following code:

def log():

ext_ip = urllib2.urlopen('http://whatismyip.org').read()

f = open('/Users/admin/Documents/%s.txt' % smush,'r')
s.storbinary("STOR /Users/admin/Documents/%s.txt" % smush,f)
Generates the following error:
ftplib.error_perm: 550 /Users/admin/Documents/678538.local # 02-24-2010 1301.txt: No such file or directory
I have a feeling something is amiss in this line :
s.storbinary("STOR /Users/admin/Documents/%s.txt" % smush,f)
678538 is the host I am testing on...using Mac OS X 10.5 and Python 2.5.1
Shouldn't it bef = open('/Users/admin/Documents/%s.txt' % smush,'r') ? notice the / in front of Users
If you dont put the first /, the script will think the path to the file is relative to the current directory (where the script is run from)
Edit:
I m not too familiar with Python (I wish) but shouldnt it be:
s.storbinary('STOR /Users/admin/Documents/%s.txt' % smush,f) ?
In your example, Python will treat your string as literal and you want to interpolate the value of smush with %s
Edit 2:
Does the directory /Users/admin/Documents/ exist on your server? If not, I think you will have to create them before copying anything. (Since the error message is about some files/folders missing).
You can create them yourself first. Run your script. If the file is copied successfully, then you can add the creation of the directories from within your script.
remove all spaces from file name .eg in smush = str(fqn +' # ' + formatdate), you are putting a space in front of and after "#". you path looks like
/Users/admin/Documents/something # something
and when you pass it to ftplib, it may have problem. another way is to try putting quotes, eg
s.storbinary("STOR '/Users/admin/Documents/%s.txt'" % smush,f)
Edit:
This version works: Problem was that I was writing to buffer, and not to file.
