#If you need compatibility with ancient versions of Python, you can either use gmpy 
#(which does include a fast, completely general int-to-string conversion function, and can 
#be built for such ancient versions – you may need to try older releases since the recent
#ones have not been tested for venerable Python and GMP releases, only somewhat recent ones)
#, or, for less speed but more convenience, use Python code – e.g., for Python 2, most 
#simply:

import string
digs = string.digits + string.ascii_letters


def int2base(x, base):
    if x < 0:
        sign = -1
    elif x == 0:
        return digs[0]
    else:
        sign = 1

    x *= sign
    digits = []

    while x:
        digits.append(digs[int(x % base)])
        x = int(x / base)

    if sign < 0:
        digits.append('-')

    digits.reverse()

    return ''.join(digits)


#For Python 3, int(x / base) leads to incorrect results, and must be changed to x // base:

import string
digs = string.digits + string.ascii_letters


def int2base(x, base):
    if x < 0:
        sign = -1
    elif x == 0:
        return digs[0]
    else:
        sign = 1

    x *= sign
    digits = []

    while x:
        digits.append(digs[x % base])
        x = x // base

    if sign < 0:
        digits.append('-')

    digits.reverse()

    return ''.join(digits)
