Output String Padding help

[northduckota]

Hello, I'd like to make my code output

10
10
0000000abc
abc0000000

What I'm I doing wrong with my code right now. All suggestions would be very much appreciated!
Here is my code

def pad_string(data, size, padding_character=' ', direction='left'):
    """This new function will determine if it will pad to the left or the right by using an if statement."""
    if direction == 'left':
        data = data.rjust(size, padding_character)
    elif data == 'right':
        data = data.ljust(size, padding_character)
    return data

def pad_left(data, size, padding_character=' '):
    """This new function will call pad_string and use it to pad to the left"""
    result_left = pad_string(data, size, padding_character, 'left')
    return result_left


def pad_right(data, size, padding_character=' '):
    """This new function will call pad_string and use it to pad to the left"""
    result_right = pad_string(data, size, padding_character, 'right')
    return result_right


# Output Test Code
print(len(pad_left('abc', 10)))
print(len(pad_right('abc', 10)))
print(pad_left('abc', 10, '0'))
print(pad_right('abc', 10, '0'))

I added between vertical bars to emphasise effect

>>> # Pad left 10
>>> print(f"|{'abs':10}|")
|abs       |
>>>
>>> # pad right 10
>>> print(f"|{'abs':>10}|")
|       abs|
>>>
>>> # zeroes to right
>>> print(f"|abc{0:07}|")
|abc0000000|
>>>
>>> # zeroes to left
>>> print(f"|{0:07}abc|")
|0000000abc|
>>>

In the function pad_string() look at the if conditions. What are you testing there? :-)

Strings have also method for filling in zeros (fills into left side): str.zfill()

>>> s = 'abc'                                                                              
>>> s.zfill(len(s))                                                                        
'abc'
>>> s.zfill(10)
'0000000abc'
