Nested Loops

Concepts: pyNestedLoops

A nested loop is a loop inside another loop. The inner loop runs completely for each iteration of the outer loop. This pattern is essential for working with multi-dimensional data structures and generating combinations. Basic Nested Loop The inner loop completes all its iterations before the outer loop moves to the next item: The outer loop runs 3 times. For each outer iteration, the inner loop runs 2 times. Total iterations: 3 x 2 = 6. Working with 2D Data Nested loops are natural for processing matrices (lists of lists): Generating Combinations Nested loops naturally generate all combinations of elements: Triangle and Pyramid Nested loops where the inner loop depends on the outer loop create triangle patterns. This is common for comparisons and hierarchical displays: In the unique pairs
