Question

Write a Python program which defines a function named "divide_two_numbers" that accepts two numeric parameters and divides the first parameter by the second. Your divide_two_numbers function must check the second parameter before dividing; if it is zero, raise an ZeroDivisionError exception which includes the string "second parameter was zero!" as a parameter instead of processing the division. Your main function must call your divide_two_numbers function at least twice; one call must use two normal parameters to verify normal operation, the other call must use zero as the second parameter to test your exception code. These calls must be enclosed in a try/except block to handle the ZeroDivisionError exception and print the string parameter if the exception is raised. Sample Output: 5 divided by 2 is 2.5 Error: second parameter was zero! Here is how I called my divide_two_numbers function from my main function, using 5 and 2 for the first call, followed by 5 and 0 for the second: print("5 divided by 2 is " + str(divide_two_numbers(5, 2))) print("5 divided by 0 is " + str(divide_two_numbers(5, 0)))

# Code

def divide_two_numbers(a,b):

if b==0:

raise ZeroDivisionError("second parameter was zero!")

return a/b

try:

print("5 divided by 2 is " + str(divide_two_numbers(5, 2)))

print("5 divided by 0 is " + str(divide_two_numbers(5, 0)))

except ZeroDivisionError as error:

print(error)

Screenshot for indentation:

4 def divide_two_numbers(a,b): if b==0: raise ZeroDivisionError("second parameter was zero!") return ab 10 try: print("5 divided by 2 is " + str(divide_two_numbers(5, 2))), print("5 divided by 0 is " + str(divide_two_numbers(5, 0))) except ZeroDivisionError as error: print(error) 13

Output:

5 divided by 2 is 2.5 second parameter was zero!
