Python: breaking down integers into exponents?

Question

I would like to make a function which convert an integer into exponents of base 27. The function should return a list with the multiple of the largest exponent in the first position and the final exponent in the last. So for example, 65 would return [2,11]. I've tried using int % b, where b is an increasing power of 27 within a loop. However it's turning out very complicated. Any help?

Answer 1

def convert(x, base):
  res = []
  while x:
    res.append(x%base)
    x //= base # this line depends on Python's version!
  res.reverse()
  return res
