What is the purpose of a while loop?

• To execute a block of code only once

• To execute a block of code as long as a specified condition is false

• To execute a block of code for a specific number of times

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

What is the syntax for a while loop in Python?

• for condition in range(): # code to be executed.

• if condition: # code to be executed.

• A loop that only executes once.

• A loop that executes a fixed number of times.

• A loop that skips certain iterations.

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

• To specify a block of code to be executed if the condition in the while loop becomes false.

• To specify a block of code to be executed if the condition in the while loop becomes true.

• To terminate the execution of the while loop.

• To skip the current iteration of the loop and move to the next iteration.

What kind of expression must be used as part of the "while" loop statement?

• mathematical expression

• assignment statement

• logical expression
