Re: How come this is different?

That's not it, Python is perfectly happy with 0x0400 as a literal.

Michael, is the code you've provided below all copied and pasted from your actual code, or did you retype any of it?  Is it all in fact at the 0-indent level and in the same file?  Likewise is that error report copied and pasted, or are you just paraphrasing?
