Programming in Python Quiz

What is the purpose of a pre-test loop?

• Check the stopping condition after executing the body

• Execute the body of the loop before checking the condition

• Skip the loop if the condition is met

• Update the loop control without executing the body

What is the main characteristic of a while loop?

• It always executes at least once

• It does not require a loop control variable

• It can only repeat a fixed number of times

• It can simulate any other type of loop

What does the break statement do in a loop?

• Repeats the current iteration

• Resets the loop control variable

• Ends the loop and exits it immediately

• Skips the current iteration and continues with the next

How is a for loop different from a while loop?

• A for loop does not require a loop control variable

• A for loop can only simulate a pre-test loop

• A for loop always executes at least once

• A for loop steps through a sequence of items

What is the purpose of a post-test loop?

• Check the stopping condition after executing the body

• Execute the body of the loop before checking the condition

• Update the loop control without executing the body

• End the loop if the condition is met

How is the range function used in a for loop?

• To check if the loop condition is met

• To skip iterations based on a condition

• To define the starting and ending values of the loop

• To specify the increment value of the loop control variable

What is the purpose of the continue statement in a loop?

• Repeats the current iteration

• Resets the loop control variable

• Skips the current iteration and continues with the next

• Ends the loop and exits it immediately

How does a sentinel controlled loop work?

• It checks the stopping condition after executing the body

• It repeats until a specific value is reached

• It executes a fixed number of times

• It uses a sentinel value to end the loop

Loop can be applied when something needs to occur multiple times

• YES

• NO

How is the range function used in a for loop?

• To specify the increment value of the loop control variable

• To check if the loop condition is met

• To define the starting and ending values of the loop

• To skip iterations based on a condition
