Python Programming Tutorial by Richard Baldwin

To the best of my knowledge, all of the program code embedded in these HTML files was originally correct. However, over time, these HTML files have been processed through a variety of website content management programs. Sometimes, such programs are not friendly to embedded code, and arbitrarily remove characters such as angle brackets, square brackets, backslashes, etc. Therefore, you may occasionally find some code that has missing characters. If so, just insert them back into the code before you attempt to compile and execute the code.
