I am currently learning Python3, but I don't understand Logical Operators. Here is the link: http://pymbook.readthedocs.org/en/py3/operatorsexpressions.html#logical-operators First of all, it seems that it is supposed to return "True" or "False" and not one of the input numbers. Second, I don't see why the output (one of the input numbers) is so. Please help, thanks.

The operator and returns the last element if no element is False (or an equivalent value, such as 0).

For example,

>>> 1 and 4
4 # Given that 4 is the last element
>>> False and 4
False # Given that there is a False element
>>> 1 and 2 and 3
3 # 3 is the last element and there are no False elements
>>> 0 and 4
False # Given that 0 is interpreted as a False element

The operator or returns the first element that is not False. If there are no such value, it returns False.

For example,

>>> 1 or 2
1 # Given that 1 is the first element that is not False
>>> 0 or 2
2 # Given that 2 is the first element not False/0
>>> 0 or False or None or 10
10 # 0 and None are also treated as False
>>> 0 or False
False # When all elements are False or equivalent
