You're right. For production, I'd probably do this.

def create_user_dirs(lines):
    for line in lines:
        pass # process lines here

with open("/etc/passwd") as fp:
    create_user_dirs(fp)

This has the benefit of allowing me to test create_user_dirs without
touching the file system (by passing in a list of lines).
