Jon Shemitz added the comment: That makes sense. Perhaps, then, the tutorial should include the FAQ? (I can't be the only person who thought to try this.) On Wed, Feb 19, 2014 at 3:59 PM, R. David Murray <report@bugs.python.org>wrote:
R. David Murray added the comment:
It's actually almost a FAQ at this point. The answer is that because of the way the parser works (it's a relatively simple parser, and we want to keep it that way), the tokenizer sees the '.' as making the token a float, and '3.__class__' is not a valid float token. So you have to precede the period by something that allows the tokenizer to know it isn't a decimal point. Parens is one way. Believe it or not, a space is another:
3 .__class__ <class 'int'>
