Answer 1

numpy.base_repr is a quite good solution, however, in some cases, we want a fixed-length string with leading zeros.

def base_repr(x: int, base: int, length: int):
    from numpy import base_repr
    from math import log, ceil
    s = base_repr(x, base, length - ceil(log(x, base)))
    return s
