In this code snippet, two nested for loops are utilized. The outer loop iterates three times while the inner loop runs three times for each iteration of the outer loop. As a result, nine combinations are printed where each pair represents a unique combination of values from both loops.

The output generated by this code would be:

0 0
0 1
0 2
1 0
1 1
1 2
2 0 
2 1 
2 2

    How do nested loops work in Python?
    • Nested loops in Python involve one loop inside another, with the inner loop executing fully during each iteration of the outer loop.

    Can I nest more than two loops in Python?

    • Yes, you can nest multiple loops within one another based on your program’s requirements. However, excessive nesting can impact readability and efficiency.

    What happens if there is a break statement inside an inner loop?

    • If a break statement is encountered within an inner loop, only that specific loop is exited immediately without affecting other enclosing loops.

    How do I avoid infinite looping with nested loops?

    • To prevent infinite looping scenarios, ensure correct looping conditions and utilize control flow statements like break or continue when necessary.

    Can I change the order of execution between nested loops?

    • Flexibility exists to adjust the sequence of execution between nested loops by modifying their placement within your code logic.


    Mastery of concepts related to embedded or nested looping scenarios equips developers with essential tools to efficiently tackle diverse challenges. By comprehensively understanding these intricacies, you elevate your ability to craft robust and elegant Python programs that stand out for their efficiency and clarity.
