Challenge: Catch an Error

Now, let's handle the error for the first time.

You should handle this error:


              
123

            
from math import sqrt

sqrt(-4)  # ValueError
copy

Since finding the square root of a negative number is not possible (according to mathematical concepts), performing this operation in Python is not feasible. The interpreter takes this into account and raises a ValueError with the following message: math domain error.

Opgave

Now, you need to complete the following points:

  1. Define the code block where an error is expected.

  2. Catch this error and print the following string:
    "The ValueError was raised!"
