How to pad with n characters in Python

Question

I should define a function pad_with_n_chars(s, n, c) that takes a string \'s\', an integer \'n\', and a character \'c\' and returns a string consisting of \'s\'

Answer 1

In Python 3.x there are string methods: ljust, rjust and center.

I created a function:

def header(txt: str, width=45, filler='-', align='c'):
    assert align in 'lcr'
    return {'l': txt.ljust, 'c': txt.center, 'r': txt.rjust}[align](width, filler)

print(header("Hello World"))
print(header("Hello World", align='l'))
print(header("Hello World", align='r'))

[Ouput]:

-----------------Hello World-----------------
Hello World----------------------------------
----------------------------------Hello World
