bool
bool([value])
Converts a value to a Boolean, using the standard truth testing procedure. If the value is false or omitted, this returns False; otherwise it returns True.
bool is also a class, which is a subclass of int. Class bool cannot be subclassed further. Its only instances are False and True.
New in version 2.2.1. Changed in version 2.3: If no argument is given, this function returns False.
