Re: Need help running external program
Thanks to all for your help it is now working, I rant he code through a debugger and found that the input file I was using to create my list of addresses to wget had newlines in them and were therefore breaking my command line. All your advice has been appreciated. RiGGa -- http://mail.python.org/mailman/listinfo/python-list

The second link is for ClientForm, the description of which reads: ClientForm is a Python module for handling HTML forms on the client side, useful for parsing HTML forms, filling them in and returning the completed forms to the server. That seems to exactly fulfil your requirements. Are you sure you really looked? Yep definately looked, but overlooked that, wasnt really looking for a premade routine to do it all but I can learn from that! thanks for pointing it out, looks like what I need Thanks -- http://mail.python.org/mailman/listinfo/python-list

How do I cut parts from a text file
Hi, I am new to Python and need to parse a text file and cut parts out i.e. say the text file contained 5 rows of text: line 1 of the text file line 2 of the text file line 3 of the text file line 4 of the text file line 5 of the text file And the text I want starts at line 2 and goes through to line 4, what is the best way to cut this text out? I guess I need to mark the start and end of the text and then pass these values to a command which will chop the file at that location however I am at a loss. Any advice or pointers of where to find more info would be greatly appreciated. Thanks RiGGa -- http://mail.python.org/mailman/listinfo/python-list
