What does the 'break' statement do in a loop?

• The 'break' statement pauses a loop.

• The 'break' statement exits a loop.

• The 'break' statement restarts the loop from the beginning.

• The 'break' statement skips the current iteration of a loop.

How does the 'continue' statement affect loop execution?

• The 'continue' statement restarts the loop from the beginning.

• The 'continue' statement ends the loop immediately.

• The 'continue' statement skips the current iteration of a loop and moves to the next iteration.

• The 'continue' statement pauses the loop for a specified time.

What is the purpose of the 'pass' statement in Python?

• The 'pass' statement is used to create a new variable in Python.

• The 'pass' statement serves as a placeholder in Python.

• The 'pass' statement is used to define a function in Python.

• The 'pass' statement is a way to exit a loop in Python.

Can 'break' be used in nested loops? If so, how?

• 'break' exits all loops at once.

• 'break' can only be used in single loops.

• Yes, 'break' can be used in nested loops to exit the innermost loop.

• 'break' cannot be used in any loops.

What will be the output of the following code: for i in range(5): if i == 3: break; print(i)

• 3

• 4

• 5

• 0 1 2

Explain a scenario where 'continue' would be useful in a loop.

• Using 'continue' to end the loop entirely.

• Using 'continue' to pause the loop for a set time.

• Using 'continue' to restart the program.

• Using 'continue' in a loop allows us to skip certain iterations based on a condition.

What happens if 'pass' is used in a function?

• The function will execute and skip the return statement.

• The function will raise an error.

• The function will execute without performing any action.

• The function will return None immediately.

Is it possible to use 'break' outside of a loop? Why or why not?

• No, it is not possible to use 'break' outside of a loop.

• Yes, 'break' can be used in any part of the code.

• 'break' can be used in functions to exit early.

• You can use 'break' in conditional statements.

How can 'continue' be used to skip even numbers in a loop?

• Use 'continue' to skip all numbers by placing it at the start of the loop.

• Use 'continue' in a loop to skip even numbers by checking if the number % 2 == 0.

• Use 'continue' to skip numbers greater than 10 by checking if the number > 10.

• Use 'continue' to skip odd numbers by checking if the number % 2 != 0.

What is the difference between 'break' and 'return' in a function?

• 'break' is used to pause execution, while 'return' continues it.

• 'break' and 'return' serve the same purpose in exiting code.

• 'break' can only be used in functions, while 'return' can be used anywhere.

• The difference is that 'break' exits loops or switch statements, whereas 'return' exits functions.
