### Python Quiz: `and` vs `or` — Operand Return Behavior
Test your Python knowledge with these 10 quiz questions, covering truthy/falsy values, short-circuit evaluation, and code output.
Key rule to remember:
* `x and y` → returns `x` if `x` is falsy; otherwise returns `y`.
* `x or y` → returns `x` if `x` is truthy; otherwise returns `y`.
Python and/or Operator Quiz

D. 8
5. What is the output? print(None or False or "Done")
A. True
B. None
C. False
D. Done
6. Select every expression that evaluates to the integer 0. # Evaluate each expression independently
A. 9 or 0
B. 9 and 0

D. 0 or 7
7. In Python, the expression "Hi" or "Bye" evaluates to the string "Hi".
True
False
8. In Python, [] and 10 evaluates to the integer 10 because and always returns its last operand.
True
False
9. What is printed? def check(): print("called") return 99 print(1 or check())
A. called, then 1
B. called, then 99
C. 99 only
D. 1 only
10. What is the output? value = "" result = value and 100 print(repr(result))
A. None
B. ''
C. 100
D. False
Quick revision tip: `and` stops at the first falsy operand; `or` stops at the first truthy operand. Both return the actual operand,
not necessarily `True` or `False`.
