Python Control Flow: Loops 2

Question 1

What does the `else` clause of a `for` loop execute?

Accepted Answer

Only if the loop completed without a `break`

Answer

The `else` clause runs after the loop finishes normally (without hitting a `break` statement).

Question 2

What is the output of: `for i in range(3): print(i, end=' ')`?

Accepted Answer

0 1 2

Answer

`range(3)` generates 0, 1, 2 — it stops before 3.

Question 3

Which loop construct is most appropriate when the number of iterations is unknown ahead of time?

Accepted Answer

`while` loop

Answer

A `while` loop continues as long as a condition is true, making it ideal when iteration count is unknown.

Question 4

What happens if the condition of a `while` loop is never `False`?

Accepted Answer

The loop runs indefinitely (infinite loop)

Answer

If the condition never becomes `False` and there's no `break`, the `while` loop runs forever.

Question 5

What does `continue` do inside a loop?

Accepted Answer

Skips the rest of the current iteration and moves to the next

Answer

`continue` skips the remaining statements in the current loop body and proceeds to the next iteration.
