why true when you call bool() from 1..

I understood when you type in python shell bool(0) it returns False but when you type bool(1) or bool(100) it returns True why is that?

Shall I think in logic way that zero means nothing and thats why it returns False?..or? :smile:

As an additional note, I can't seem to find any truthy/falsey documentation for Python 3. But to my knowledge, it hasn't changed from Python 2. You can see some documentation here about what classifies as "falsey" in Python.
