This vids is a quick lesson on permutation, a side discussion of permutation using python. The permutation was mentioned in my previous vids in "Learning Javascript"
What is permutation?In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements. The word "permutation" also refers to the act or process of changing the linear order of an ordered set. - Wikepedia
Test this short codes and play with the different sets of data to write your permutation app in python. Have fun!
