Error handling by raising an error

Another way to raise an error is by using raise. In this exercise, you will add a raise statement to the shout_echo() function you defined before to raise an error message when the value supplied by the user to the echo argument is less than 0.

The call to shout_echo() uses valid argument values. To test and see how the raise statement works, simply change the value for the echo argument to a negative value. Don't forget to change it back to valid values to move on to the next exercise!

Instructions

Complete the if statement by checking if the value of echo is less than 0.
In the body of the if statement, add a raise statement that raises the error message 'echo must be greater than 0' when the value supplied by the user to echo is less than 0.
