The permutations() function gives us different ways to reorder a given set of values. The combinations() function returns all the possible subsets of the original set.

We also looked at ways in which the product() and permutations() functions can be used naively to create extremely large result sets. This is an important cautionary note. A succinct and expressive algorithm can also involve a vast amount of computation. ...
