That's just plain evil. > Reading on the Python website, a tab size of 8 is default anyway, so I would > have assumed it should work... does that mean that one tab equals 2 > indents?!?

Or maybe I am > completely on the wron track here? 4-space indents are /recommended/ by PEP 8, but the interpreter does not require or prefer that style. What the interpreter does when parsing indentation is rather more complicated; see http://docs.python.org/reference/lexical_analysis.html#indentation You might wanna look at tabnanny: http://docs.python.org/library/tabnanny.html Cheers, Chris -- http://mail.python.org/mailman/listinfo/python-list
