**Counting all permutations of a substring Python**

This will give a exact value for your combination and I'm sure python has some floor() function. Otherwise, you always can use pygsl to access GSL special functions . Note that this formula do not make use of recursion and calculation of gamma function values are essentially an O(1) operation.... Python Basic - 1: Exercise-13 with Solution. Write a Python program to get all possible two digit letter combinations from a digit (1 to 9) string.

I believe you want itertools.product(String[0],String[1],…) This is easy enough when you know how many strings there are to put in the arguments for itertools.product. If that number is also dynamic, you need the equivalent of apply, which in python is done like this: how to drink wine properly Write a Python program to print all permutations of a given string (including duplicates).
