not nonchalant. i know i will ned to do testing and whatnot. just personally, i like to build stuff one concept at a time. for example, i had a problem with the homedir and peopel here helped me with that. now i have permissions problem, and an swer will likely meeerge. once i know how to copy a file, ill work on testing. like isfile and permissions. i know that has to be done. i guess its that you want tests before moves , and thats fine. since i have only ever had 1 python class, and basically learning this whole thing from scratch, i need to do things 1 step at a time. so now any thoughts on why i cannot write to my own homedir? -- http://mail.python.org/mailman/listinfo/python-list
