list - How to dislpay only the names of the users when opening /etc/group in Python? -

-

this code: 

grouplist = open("/etc/group" , "r") grouplist f2:     open("group" , "w+") f1:     f1.write(f2.read())     f1.seek(0,0)     command = f1.read()     print     print command

what command can use make display names of users without ":x:1000:"

you achieved target. little fix in code, here solution.

 open("/etc/group" , "r") source:     open("./group" , "w+") destination:         destination.write(source.read())         source.seek(0,0)         user in source.readlines():             print user[: user.index(':')]

nevertheless, show names, still copy original file.

this way write names in new file.

with open("/etc/group" , "r") source:     open("./group" , "w+") destination:         user in source.readlines():             u = user[: user.index(':')]             destination.write('%s\n' % u)             print u
