convert int to other bases

[bowlofred]

This one creates strings suitable for putting back into int(x, base=36). Not as useful for arbitrarily large bases.

import string
import random

base = 36
mapping = string.digits + string.ascii_uppercase

def int_to_other_base(num, base):
    ans = ""
    while num > 0:
        num, remainder = divmod(num, base)
        ans = mapping[remainder] + ans
    return ans

num = random.randint(0,1000000000000000)

print(f"For integer {num}")
rebased = int_to_other_base(num,base)
print(f"In base {base}: {rebased}")
print(f"and converted back to an int: {int(rebased,base)}")

Output:
For integer 19520920808903
In base 36: 6X3SC8FRB
and converted back to an int: 19520920808903
