Make division by zero equal to zero

Question

How can I ignore ZeroDivisionError and make n / 0 == 0?

Answer 1

Check if the denominator is zero before dividing. This avoids the overhead of catching the exception, which may be more efficient if you expect to be dividing by zero a lot.

def weird_division(n, d):
    return n / d if d else 0

Answer 2

You can use a try/except block for this.

def foo(x,y):
    try:
        return x/y
    except ZeroDivisionError:
        return 0

>>> foo(5,0)
0

>>> foo(6,2)
3.0
