How to Throw an Exception If a Condition Occurs in Python


In this example, we will learn how to throw an exception if a condition occurs using the raise keyword in Python.

Source Code

 exception
num = 16

if num > 10:
    raise Exception("'num' can't be greater than 10. 'num' is: {}".format(num))

Output:
