Generating association rules

As you saw, the function permutations from the module itertools can be used to quickly generate the set of all one-antecedent, one-consequent rules. You do not, of course, know which of these rules are useful. You simply know that each is a valid way to combine two items.

Let's practice generating and counting the set of all rules for a subset of the grocery dataset: coffee, tea, milk, and sugar.

Instructions

100 XP
  • Complete the import statement to import the permutations function.
  • Generate all association rules from the groceries list.
  • Print the set of rules.
  • Print the number of rules.
