![Error Python: [Zerodivisionerror: Division by Zero]](https://docuprint.cloud68.co/uploads/error-python-zerodivisionerror-division-by-zero_1200.jpg)
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

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
# 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)
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
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
