I am reading the book Think Python by Allen Downey. For chapter 4, one has to use a suite of modules called Swampy. I have downloaded and installed it.
The problem is that the modules were written in Python 2 and I have Python 3 (in Windows 7 RC1). When I ran the TurtleWorld module from Swampy, I got error messages about the print and exec statements, which are now functions in Python 3. I fixed those errors by including parentheses with print and exec in the code of the GUI and World modules. I also got an error that the Tkinter module could not be found. It turned out that in Python 3, the module name is spelled with a lower case t.
The third error is more difficult: ImportError: No module named tkFont.
Does anyone have any idea, please? Thank you.
