Convert an integer to boolean in python

To convert an integer to boolean in python, one can use the bool() function, example:

>>> n = 1
>>> bool(n)
True
>>> n = 0
>>> bool(n)
False

Note that if the number is not 0, bool() always returns True:

>>> n = 9
>>> bool(n)
True
>>> n = -1
>>> bool(n)
True
