What is the expected output of the following code? x = True y = False x = x or y x = x and y x = x or y print(x, y)

Question

Options

• ATrue True
• BTrue False
• CFalse False
• DFalse True

• A
  6% (1)
• B
  71% (12)
• C
  18% (3)
• D
  6% (1)

Explanation

There's an error in the stated correct answer. Tracing the code step by step reveals the actual output is False False (option C), not True False.

Here's the trace:

Why C is correct: The third assignment x = x and y sets x to False (since y is always False). The final x = x or y is then False or False, keeping x as False. y is never reassigned, so it stays False.

Why the distractors are wrong:

• A (True True): y is never changed, so it can never print True.
• B (True False): This would require x to remain True after the and operation, but True and False = False.
• D (False True): Again, y is never modified.

Memory tip: With chained boolean assignments, note which variable y never changes - it's always False. Any and y will collapse the result to False, and or y can never rescue it back to True.
