    Question 1

    What does the following Python code do?

    Python 
    count = 0
while count < 5:
   print("Count:", count)
   count += 1
   if count == 3:
       continue
   print("After Continue")

    • Prints "Count: 0" to "Count: 4" with "After Continue" after each line.

    • Prints "Count: 0" to "Count: 2" with "After Continue" after each line.

    • Prints "Count: 0" to "Count: 4" without "After Continue" after "Count: 2"

    • Raises a SyntaxError.

    Question 2

    How can you iterate over the items of a list using a while loop?

    • Use a for loop instead.

    • Use the range function with the length of the list.

    • Convert the list to a set and iterate over it.

    • Use the enumerate function.

    Question 3

    In Python, can a while loop be used to iterate over a dictionary directly?

    • Yes

    • No

    • Only if the dictionary keys are integers.

    • Only if the dictionary has a single key.

    Question 4

     In Python, how can you emulate the behavior of a break statement inside a while loop without using bre

    • Use a return statement.

    • Use a pass statement.

    • Raise a custom exception.

    • Use a goto statement.

    Question 5

    In Python, can a while loop have multiple else blocks?

    • Yes

    • No

    • Only if the loop has multiple conditions.

    • Only if the loop uses nested if statements.

    Question 6

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

    • To terminate the loop.

    • To check if a condition is true and raise an error if not.

    • To skip the rest of the code in the loop.

    • It is not a valid statement in a while loop.

    Question 7

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

    • It always runs after the loop completes.

    • It is used to handle exceptions within the loop.

    • It runs if the loop encounters an error.

    • It runs if the loop completes without encountering a break statement.

    Question 8

    How does the while-else construct work in Python?

    • It is not a valid construct in Python.

    • The else block always runs after the loop.

    • The else block runs if the loop encounters an error.

    • The else block runs if the loop completes without encountering a break statement.

    Question 9

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

    • Terminates the loop.

    • Skips the remaining code in the loop and moves to the next iteration.

    • Exits the loop prematurely.

    • Breaks out of the loop entirely.

    Question 10

    What is the output of the following Python code?

    Python 
    num = 2
while num < 10:
   print(num, end=" ")
   num **= 2

    • Prints powers of 2 from 2 to 8.

    • Prints the square of numbers from 2 to 10.

    • Prints numbers in the range [2, 10) with a step of 2.

    • Raises a SyntaxError.
