Question 10

How does a 'while' loop differ from a 'for' loop in Python?

Accepted Answer

A 'while' loop is used when you don't know the number of iterations in advance, while a 'for' loop is used when you know the number of iterations

Answer

A 'while' loop is used for mathematical calculations, while a 'for' loop is used for text manipulation

Answer

A 'while' loop always runs an infinite number of times, while a 'for' loop runs a predefined number of times

Answer

A 'while' loop can only iterate over numbers, while a 'for' loop can iterate over strings

Answer

A 'while' loop can skip iterations, while a 'for' loop cannot

Answer

To skip the current iteration and move to the next one

Answer

To restart the loop from the beginning

Question 13

How can you prevent an infinite loop in Python while using a while loop?

Accepted Answer

By ensuring the loop variable is updated inside the loop

Answer

By increasing the loop variable by a fixed amount each iteration

Answer

By using the 'continue' statement instead of 'break'

Answer

By changing the loop condition to always evaluate to True

Question 14

What happens if the condition of a while loop in Python is initially False?

Accepted Answer

The loop body will not be executed

Answer

The loop will throw an error

Answer

The loop will run indefinitely

Answer

The loop body will be executed only once

Question 15

How do you ensure a while loop in Python eventually terminates?

Accepted Answer

By adjusting the loop variable to meet the loop condition

Answer

By using the 'stop' keyword to end the loop

Answer

By decreasing the loop variable infinitely

Answer

By adding more code inside the loop

Question 16

What is the role of the 'continue' statement in a while loop in Python?

Accepted Answer

To skip the current iteration and move to the next one

Answer

To print the loop variable

Answer

To exit the loop prematurely

Answer

To restart the loop from the beginning

Question 17

What would happen if you forget to update the loop variable in a while loop in Python?

Accepted Answer

The loop may result in an infinite loop

Answer

The loop will automatically terminate after one iteration

Answer

The loop will throw an error

Answer

The loop will skip certain iterations

Question 18

How can you exit a while loop in Python based on a specific condition?

Accepted Answer

Using the 'break' statement

Answer

Using the 'continue' statement

Answer

Using a 'return' statement

Answer

Using the 'skip' keyword

Question 19
