A
if day_of_week = 1 and review_period:
B
if day_of_week = 1 and review_period == "True":
C
if day_of_week == 1 and review_period == "True":
D
if day_of_week == 1 and review_period:
E
if day_of_week == 1 & review_period: = "True":
Explanation:
The correct answer is D because:
- Proper comparison operator: Uses
==(equality comparison) instead of=(assignment) forday_of_week - Correct boolean evaluation: Uses
review_perioddirectly without quotes, which correctly evaluates the boolean variable - Valid Python syntax: Uses
andoperator (not&which is bitwise AND)
Why other options are incorrect:
- A: Uses
=(assignment) instead of==(comparison) - B: Uses
=(assignment) and comparesreview_periodto string "True" instead of boolean True - C: Compares
review_periodto string "True" instead of boolean True - E: Uses bitwise
&operator instead of logicaland, and has invalid syntax with= "True":
