Why this function returns only a digit 2 instead of numbers from 1 to 100?

def display_even_digits(a, b):
    for digit in range(a, b):
        if digit % 2 == 0:
            return digit

print(display_even_digits(1, 101))
🟢 Solution

You are returning the first even number, you need to return all numbers. You could just find if a is even and if not add 1 and then use the step argument of range.

def display_even_digits(a, b):
    return list(range(a + a % 2, b, 2))

print(display_even_digits(1, 101))
