Cartesian Product

Mentioned during a lecture of the Missing Semester of CS when explaining advanced methods of shell globbing with curly brackets {}

A mathematical concept that combines every element of one set with every element of another set, resulting in a new set of pairs or tuples representing all possible combinations between the two sets.

set_a = {1, 2}
set_b = {x, y}
 
# Cartesian product
{
	 [1, x],
	 [1, y],
	 [2, x],
	 [2, y]
 }
