The Complete Ethical Hacking Bootcamp: Beginner To Advanced - While Loop

This video tutorial covers the basics of while loops in Python, including their syntax and usage. It demonstrates how to create infinite loops and how to use conditions to break out of loops. The tutorial also explores combining while loops with if-else statements to create more complex programs. Finally, it concludes with a brief introduction to lists, which will be covered in the next video.

What is the primary purpose of a while loop in Python?

• To execute a block of code only once

• To execute a block of code as long as a condition is true

• To execute a block of code based on user input

• To execute a block of code a fixed number of times

How can you stop an infinite loop in Python?

• By using the 'stop' command

• By closing the Python interpreter

• By using 'Ctrl + C' to interrupt

• By waiting for it to finish

What happens if the condition in a while loop is always true?

• The loop will execute twice

• The loop will never execute

• The loop will execute once

• The loop will execute indefinitely

What is the result of setting a Boolean variable to false in a while loop condition?

• The loop will execute once

• The loop will execute indefinitely

• The loop will execute twice

• The loop will not execute

How does a break statement affect a while loop?

• It pauses the loop temporarily

• It ends the loop immediately

• It skips the current iteration

• It restarts the loop

In the example program, what input causes the loop to terminate?

• Typing 'end'

• Typing 'Q'

• Typing 'stop'

• Typing 'exit'

What is the role of the if-else statement in the example program?

• To provide an alternative action if the loop condition is false

• To execute code only once

• To check user input and decide whether to continue or break the loop

• To execute code only if a condition is false
