You can do exponents either with the ** operator or the pow() function: py> 2**4 16 py> pow(3, 5) 243 The pow() function is especially useful for advanced mathematics where you want to perform exponents modulo some base: py> pow(3, 5, 2) 1 That is, it calculates the remainder when divided by 2 of 3**5 *without* needing to calculate 3**5 first. This is especially useful when the intermediate number could be huge: py> pow(1357924680, 2468013579, 1256711) 418453L To get the remainder, use the % operator or the divmod() function: py> 17 % 2 1 py> divmod(17, 2) (8, 1) Hope this helps.
