Python base 36 encoding

by

Have you tried Wikipedia’s sample code?

def base36encode(number, alphabet="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"):
    """Converts an integer to a base36 string."""
    if not isinstance(number, int):
        raise TypeError('number must be an integer')
 
    base36 = ''
    sign = ''
 
    if number < 0:
        sign = '-'
        number = -number
 
    if 0 <= number < len(alphabet):
        return sign + alphabet[number]
 
    while number != 0:
        number, i = divmod(number, len(alphabet))
        base36 = alphabet[i] + base36
 
    return sign + base36
 
def base36decode(number):
    return int(number, 36)
 
print(base36encode(1412823931503067241))
print(base36decode('AQF8AA0006EH'))
