Loops in Python

This video tutorial introduces the concept of loops in programming, focusing on for and while loops in Python. It explains how loops allow for the repetition of instructions until a condition is met. The tutorial provides examples of using for loops to search for numbers in a list and optimize the process with break and continue statements. It also covers while loops with a practical example of adding weights to a box, demonstrating how to enhance the code for better performance.

What is the primary purpose of a loop in programming?

• To define a new function

• To repeat a sequence of instructions until a condition is met

• To store data in a structured format

• To execute a sequence of instructions once

Which statement is used to exit a loop immediately in Python?

• continue

• exit

• break

• stop

What does the 'continue' statement do in a loop?

• Exits the loop

• Skips the current iteration and continues with the next

• Restarts the loop from the beginning

• Ends the program

In a while loop, when does the loop stop executing?

• When the loop has iterated a fixed number of times

• When the condition becomes false

• When the loop encounters a 'break' statement

• When the loop encounters a 'continue' statement

What is a potential use case for a while loop?

• Storing data in a dictionary

• Defining a new function

• Executing a block of code as long as a condition is true

• Iterating over a fixed list of items
