Question 1
What does the following Python code do?
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: 3".
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?
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.
