Thank you Kent, I've done the modifications you suggested, and the code follows. I splitted the __init__ method in four methods (__init__, header, footer, dir_browser) and took the get_file_names out of pyrun class. Now I have two more general questions, if you don't mind. 1) (first a philosoph

[Tutor] Comparing times

Hello there, I need to be able to compare time on a process tree with system time, and take action accordingly. Here's how I get the time on the process tree: >>> for line in os.popen("ps -ef", "r"): ... if "telnet" in line: ... print line.split()[4] ... 11:00:25 11:01:31 10:01:
