In Python programming, let N be an integer variable (identifier). Evaluate the following Boolean expression according to Python operator precedence rules:
10 != 20 or 30 == 40 and not 50 > N
Which of the following statements correctly describes the result of this Boolean expression?
- A.
Always True
- B.
Always False
- C.
True only if 50 > N
- D.
False only if 50 > N
Attempted by 219 students.
Show answer & explanation
Correct answer: A
Evaluate the expression using operator precedence:
10 != 20 or 30 == 40 and not 50 > N
Step 1: Relational operators
10 != 20 → True
30 == 40 → False
50 > N → depends on N
Step 2: not operator
not (50 > N)
Step 3: and operator
False and (not 50 > N) → always False (because False AND anything = False)
Step 4: or operator
True or False → True
So, the overall expression is always True regardless of the value of N.
Correct answer: Option A (Always True)
