How to do cartesian product in python
WebOct 19, 2024 · The Cartesian Product has 3 x 3 = 9 elements. In general, if there are m elements in set A and n elements in B, the number of elements in the Cartesian Product is m x n Given two finite non-empty sets, write a program to print Cartesian Product. Examples : Input : A = {1, 2}, B = {3, 4} Output : A × B = { {1, 3}, {1, 4}, {2, 3}, {2, 4}} Mathematically, a Cartesian product is a set, so a Cartesian product does not contain duplicates. On the other hand, itertools.product will have duplicates in the output if the inputs have duplicates. So itertools.product is not strictly speaking the Cartesian product, unless you wrap the inputs in set, as mentioned by @CamilB. –
