How to Do a Permutation in Python
- 1). Import the "itertools" module:
import itertools - 2). Assign all values in the set to a variable. Suppose that you need to determine the number of ways 2 members from a sorority of 5 students could be elected into positions as Vice President and President. Assuming their names are Angela, Cindy, Jan, Marsha and Beyonce, you would type the following command:
permutation_set_variable = ['Angela', 'Cindy', 'Jan', 'Marsha', 'Beyonce'] - 3). Call the "permutations" function in the following form:
itertools.permutations(set, r) - 4). Replace "set" with the variable containing the values and "r" with the length required. Given the example, you would type the following:
itertools.permutations(permutation_set_variable, 2)
