[python] Check if value is zero or not null in python

Often I am checking if a number variable number has a value with if number but sometimes the number could be zero. So I solve this by if number or number == 0.

Can I do this in a smarter way? I think it's a bit ugly to check if value is zero separately.

Edit

I think I could just check if the value is a number with

def is_number(s):
    try:
        int(s)
        return True
    except ValueError:
        return False

but then I will still need to check with if number and is_number(number).

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

You can check if it can be converted to decimal. If yes, then its a number

from decimal import Decimal

def is_number(value):
    try:
        value = Decimal(value)
        return True
    except:
        return False

print is_number(None)   // False
print is_number(0)      // True
print is_number(2.3)    // True
print is_number('2.3')  // True (caveat!)

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

if number or number==0:
    return True
