for line in files:
    with open(file) as lines:
        for line in lines: # you can iterate over the file directly;
                           # no need for the intermediate list built by
                           # the readlines() method
            line = line.partition("#")[0] # remove comment
            line = line.rstrip() # remove trailing whitespace
            policy_lines.append(line)
            print line


If you want to keep trailing whitespace other than the newline replace

line = line.rstrip()

with 

line = line.rstrip("\n\r")
