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

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.
