I just read in the 'What's New in Python 2.4' document that the None data type was converted to a constant: http://python.org/doc/2.4/whatsnew/node15.html
""" # None is now a constant; code that binds a new value to the name "None" is now a syntax error. """ So, what's the implications of this? I find the lack of explanation a little puzzling, since I've written code that compares a variable's type with the 'None' type. For example, a variable would be initialized to 'None' and if it went through a loop unchanged, I could determine this at the end by using a conditional type(var) == type(None). What will type(None) return now? -- http://mail.python.org/mailman/listinfo/python-list
