basic script to convert base (ints only)

bases.py

def convert_base(val, og_digits="0123456789", new_digits="0123456789"):
    og_digits, new_digits = list(og_digits), list(new_digits)
    og_base, new_base = len(og_digits), len(new_digits)

    b10 = 0
    val = str(val)
    for i, digit in enumerate(val):
        b10 += og_digits.index(digit) * og_base ** (len(val) - i - 1)

    ret = ''
    while b10 >= 1:
        ret = f"{new_digits[int(b10 % new_base)]}{ret}"
        b10 /= new_base

    return ret
