Python Control Flow: Conditional Statements 2

Question 1

What does the following code print?

x = 10
if x > 5:
    print('A')
elif x > 8:
    print('B')
else:
    print('C')

Accepted Answer

A

Answer

The first condition `x > 5` is True, so 'A' is printed and the rest of the elif/else chain is skipped.

Question 2

Which operator is used for the ternary (conditional) expression in Python?

Accepted Answer

if/else inline

Answer

Python uses `value_if_true if condition else value_if_false` as its ternary expression syntax.

Question 3

What is the output of: `print('yes' if 0 else 'no')`?

Accepted Answer

no

Answer

0 is falsy in Python, so the else branch evaluates and 'no' is printed.

Question 4

Which of the following is a valid Python conditional expression?

Accepted Answer

x = a if a > b else b

Answer

Python's conditional (ternary) expression syntax is `value_if_true if condition else value_if_false`.

Question 5

What happens if no `elif` or `else` clause is present and the `if` condition is False?

Accepted Answer

Nothing happens; execution continues after the block

Answer

If the `if` condition is False and there are no other branches, Python simply skips the block and continues.
