Beginner Tutorials
Hi, I've developed a website for beginners to Python. I'd appreciate any comments or criticism. It's still under development, and should be finished in the next few months. Oh, and it's free to use. www.usingpython.com -- http://mail.python.org/mailman/listinfo/python-list
Re: Beginner Tutorials
Thanks for the comments. I have changed the headings to lower case as you suggested. The site was created in wordpress using a standard theme, and linked pages rather than posts. i'd recommend using it to quickly set up a site; i started developing my own site but wanted to focus on site content and not HTML! > You have done well Rik.

Re: Beginner Tutorials
The reason for disabling right-click has nothing to do with protecting content, and everything to do with stopping my students from taking the lazy way out. Given the chance, they'll copy/paste the code and download the designs and edit them slightly. They'd get through the tutorials in about 25 minutes and have learnt next to nothing. In talking to students about existing resources, they said that blindly copying code didn't really help them get a deep understanding of algorithms and how to apply them to other problems. In the password-protected solutions i will provide downloads to source code, etc, and any student smart enough to get around my protection probably understands python basics :) Thanks for the comments. -- http://mail.python.org/mailman/listinfo/python-list

Try calling > Profile.run(doSomething) # no parenthesis for doSomething. i'm reading your message more carefully, and so tried calling profile.run(main), without any parens (and absorbing the argument into the function's body for this test). same error!? -- http://mail.python.org/mailman/listinfo/python-list

your hint and REREADING THE DOCUMENTATION made me realize it
was the QUOTE MARKS on the function call i was missing:
profile.run('main(seedFile)','profileOutFile')
Harit, perhaps this was your problem, too?
Ben, thanks for your help.
