Control Flow: Conditional Statements Flashcards

What does the following code print? x = 10 if x > 5: print('A') elif x > 8: print('B') else: print('C')

Answer: A

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

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

Answer: if/else inline

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

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

Answer: no

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

Which of the following is a valid Python conditional expression?

Answer: x = a if a > b else b

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

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

Answer: Nothing happens; execution continues after the block

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

What is the result of the following? age = 20 status = 'adult' if age >= 18 else 'minor' print(status)

Answer: adult

Since `age >= 18` is True, the ternary expression evaluates to 'adult'.

In Python, how many `elif` clauses can follow a single `if` statement?

Answer: Unlimited

Python allows any number of `elif` clauses after an `if` statement.
