: Write a Python function named "is_even" that takes an integer as input and returns True if the number is even, and False otherwise

Sure! Here's the Python code for the `is_even` function that takes an integer as input and returns `True` if the number is even, and `False` otherwise:

def is_even(num):
    if num % 2 == 0:
        return True
    else:
        return False

You can call this function by passing an integer as an argument like this:

print(is_even(4))  # Output: True
print(is_even(5))  # Output: False

In the first call to the function, the input `4` is an even number, so the function returns `True`. In the second call to the function, the input `5` is an odd number, so the function returns `False`.
