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'>
