Question

PYTHON: Write a function count_evens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2).

Ex: If the four parameters are:

1

22

11

40

then the returned count will be:

Total evens: 2

Hint: Use the modulo operator % to determine if each number is even or odd.

Your program must define the function:

count_evens(num1, num2, num3, num4)

Answer 1

The Python function count_evens() calculates the count of even parameters among four integers using the modulo operator and returns the count.

Step-by-step explanation:

The function count_evens() will iterate over the four integer parameters and use the modulo operator (%) to determine if each number is even. The function increments a count whenever an even number is found and returns the final count of even numbers.

Example Python Function:

def count_evens(num1, num2, num3, num4):
count = 0
for num in (num1, num2, num3, num4):
if num % 2 == 0:
count += 1
return count

For the provided example parameters (1, 22, 11, 40), the function will return 2 indicating two even parameters were found.
