Hello, I'm trying to do the following: I have a list that is all the lines from the password file. if I did print p[0] # p being a line in /etc/passwd I would get: uucp:x:10:14:uucp:/var/spool/uucp: or whatever. My question is how do process this list into another list with just everything before the first ":". I'm not quite sure how to do this.
