The term Cartesian product refers to the idea of enumerating all the possible combinations of elements drawn from a number of sets.
Mathematically, we might say that the product of two sets,
, has 52 pairs, as follows:
{(1, C), (1, D), (1, H), (1, S), (2, C), (2, D), (2, H), (2, S), ..., (13, C), (13, D), (13, H), (13, S)}
We can produce the preceding results by executing the following commands:
>>> list(product(range(1, 14), '♣♦♥♠')) [(1, '♣'), (1, '♦'), (1, '♥'), (1, '♠'), (2, '♣'), (2, '♦'), (2, '♥'), (2, '♠'),... (13, '♣'), (13, '♦'), (13, '♥'), (13, '♠')]
The calculation of a product can be extended ...
