Welcome back to another coding exercise solution!

This is my solution to the coding exercise. Again, it may be slightly different from yours!

"""
for the function below, add your code in appropriate place that checks the input n.
n should be a non-negative integer, otherwise a ValueError should be raised
and a proper error message should be provided informing the user of the error
for simplicity, you may assume that the input is always an integer for this exercise
"""

def count_from_zero_to_n(n):
    if n < 0:
        raise ValueError('Input should be a non-negative integer')
    for x in range(0, n+1):
        print(x)

Let me know how you got on!

Kind regards,
