Check if value is zero or not null in python

The simpler way:

h = ''
i = None
j = 0
k = 1
print h or i or j or k

Will print 1

print k or j or i or h

Will print 1

If number could be None or a number, and you wanted to include 0, filter on None instead:

if number is not None:

If number can be any number of types, test for the type; you can test for just int or a combination of types with a tuple:

if isinstance(number, int):  # it is an integer
if isinstance(number, (int, float)):  # it is an integer or a float

or perhaps:

from numbers import Number

if isinstance(number, Number):

to allow for integers, floats, complex numbers, Decimal and Fraction objects.

Zero and None both treated as same for if block, below code should work fine.

if number or number==0:
    return True

DO NOT USE:

if number or number == 0:
    return true

this will check "number == 0" even if it is None. You can check for None and if it's value is 0:

if number and number == 0:
    return true

Python checks the conditions from left to right: https://docs.python.org/3/reference/expressions.html#evaluation-order
