Understanding While Loops in Python

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

• To execute a block of code once

• To iterate over a block of code as long as the test condition is true

• To iterate over a block of code a fixed number of times

• To filter items out of a sequence

What is the key difference between a for loop and a while loop?

• A for loop can iterate over sequences, while a while loop cannot

• A while loop can only execute if a condition is false

• There is no difference

• A for loop iterates over the entire sequence regardless of a condition, while a while loop continues as long as a specific condition is met

What happens when the test condition in a while loop becomes false?

• The loop executes one last time before stopping

• The loop restarts from the beginning

• The loop skips the next iteration

• The loop immediately stops

How can you create a counter in a while loop?

• By using a break statement

• By incrementing a variable within the loop

• By using a continue statement

• By setting a fixed number of iterations before the loop starts

What does the break statement do in a while loop?

• It pauses the execution of the loop

• It restarts the loop from the beginning

• It skips the current iteration and continues with the next one

• It stops the loop even if the while condition is true

What is the purpose of the else statement in a while loop?

• To catch any errors that occur within the loop

• To execute a block of code if the loop never runs

• To execute a block of code before the loop starts

• To execute a block of code once the loop condition becomes false

What effect does the continue statement have inside a while loop?

• It pauses the loop execution temporarily

• It resets the loop's condition to true

• It skips all remaining statements in the current iteration and proceeds to the next iteration

• It causes the loop to exit

What will happen if a continue statement is used without modifying the loop's condition?

• The loop may enter an infinite loop if the condition is not updated

• The loop will execute the remaining code in the block before continuing

• The loop will skip to the next condition check without executing further code in the block

• The loop will terminate immediately
