Error Python: [Zerodivisionerror: Division by Zero]

Question

I faced an error when I run my program using python: The error is like this:

ZeroDivisionError: division by zero

My program is similar to this:

In [55]:

x = 0
y = 0
z = x/y
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
<ipython-input-55-30b5d8268cca> in <module>()
      1 x = 0
      2 y = 0
----> 3 z = x/y

ZeroDivisionError: division by zero

Thus, I want to ask, how to avoid that error in python. My desired output is z = 0

Accepted Answer

Catch the error and handle it:

try:
    z = x / y
except ZeroDivisionError:
    z = 0

Or check before you do the division:

if y == 0:
    z = 0
else:
    z = x / y

The latter can be reduced to:

z = 0 if y == 0 else (x / y)

Or if you're sure y is a number, which implies it`s truthy if nonzero:

z = (x / y) if y else 0
z = y and (x / y)   # alternate version

Answer 2

# we are dividing until correct data is given
executed = False
while not executed:
    try:
        a = float(input('first number --> '))
        b = float(input('second number --> '))
        z = a / b
        print(z)
        executed = True
    except ArithmeticError as arithmeticError:
        print(arithmeticError)
    except ValueError as valueError:
        print(valueError)
    except Exception as exception:
        print(exception)

Answer 3

Returning zero instead of the division by zero error can be accomplished with a Boolean operation.

z = y and (x / y)

Boolean operations are evaluated left to right and return the operand, not True or False.

If y is 0, the value returned is y. If y is different from 0, the right side of the operation is executed and the value returned is x / y

Answer 4

ZeroDivisionError: division by zero

a = 10
b = 0
c = a/b

This would cause the type error because you are dividing by zero.

To solve this issue:

a = 10
b = 0
c = ( a / b ) if b != 0 else 0
print c
