Evenness Function

In a file called evenness_function.py …

Write a function like so:

def is_even(n: int) -> bool:
    """Determine if a number is even.

    Args:
        n: the number to check
    
    Returns:
        True if the number is even, False otherwise.
    """

Also write:

def is_divisible_by_3(n: int) -> bool:
    """Determines if a number is evenly divisible by 3.

    Args:
        n: The number to check
    
    Returns:
        True if the number is divisible by 3. False otherwise.
    """

Write a main() funciton that contains a for loop to generate all the numbers from 1 to 20. Use if statements inside the loop to mark the number with a "<" if it’s even, with a "=" if it’s evenly divisible by 3, and with both if it’s divisible by both 2 and 3.

1
2 <
3 =
4 <
5
6 <
6 =
7
8 <
9 =
10 <
11
12 <
12 =
13
14 <
15 =
16 <
17
18 <
18 =
19
20 <

If you’re cool, it’s possible to make the display like this:

1
2 <
3 =
4 <
5
6 <=
7
8 <
9 =
10 <
11
12 <=
13
14 <
15 =
16 <
17
18 <=
19
20 <
