Python allows easy creation of an integer from a string of a given base via
int(str, base).
I want to perform the inverse: creati
Surprisingly, people were giving only solutions that convert to small bases (smaller then the length of the English alphabet). There was no attempt to give a solution which converts to any arbitrary base from 2 to infinity.
So here is a super simple solution:
def numberToBase(n, b):
if n == 0:
return [0]
digits = []
while n:
digits.append(int(n % b))
n //= b
return digits[::-1]
so if you need to convert some super huge number to the base 577
,
numberToBase(67854 ** 15 - 102, 577)
, will give you a correct solution:
[4, 473, 131, 96, 431, 285, 524, 486, 28, 23, 16, 82, 292, 538, 149, 25, 41, 483, 100, 517, 131, 28, 0, 435, 197, 264, 455]
,
Which you can later convert to any base you want
