i = 1while i < 4:    print(i)    i += 1else:    print("Loop finished")

1 2 3 Loop finished

1 2 3 4

Loop finished

1 2 3

2 / 25

B) What is a generator in Python?

A type of collection

A function that returns an iterator

A loop that can iterate once

A module for generating random numbers

3 / 25

C) Which of the following is NOT a valid reason to use a for loop in Python?

To iterate over a list

To execute a block of code a fixed number of times

To wait for a user input

To access each key-value pair in a dictionary

4 / 25

D) Which of the following is true about nested loops in Python?

The inner loop must be a while loop.

The outer loop executes once for each iteration of the inner loop.

The inner loop completes all its iterations for each iteration of the outer loop.

Nested loops can only be used with lists, not with other data structures.

E) What is the output of the following code?

for i in range(3):    for j in range(2):        if i == j:            continue        print(f"{i} {j}")

0 1 1 0 2 0 2 1

They are the only way to create lists in Python

7 / 25

G) How can the performance of a Python loop be optimized when working with large datasets?

By adding more conditional checks inside the loop

By moving computations outside the loop where possible

By using more loops for clarity

By manually managing memory allocation

8 / 25

wait

async

await

pass

continue

break

exit

17 / 25
