Nested Loops
Explore how nested loops work by using an outer and an inner loop to solve programming problems. Understand constructing Cartesian products and drawing shapes with loops, enhancing your skills in Python repetition structures.
Nested loop
When we use a loop inside another loop, we call them nested loops. The first loop is called the outer loop, and the second loop is called the inner loop. Nested loops can be the same type or different types of loops. Both loops can be for loops or while loops. The outer loop can be a for loop and the inner loop a while loop, or vice versa.
Let’s use the Cartesian product of two sets as an illustration of nested loops.
