Explanation:
🔹 Step 1: Understand Operator Priority
and has higher priority than or
So Python first evaluates:
[1] and 7
Expression becomes:
[] or 0 or False or 7
🔹 Step 2: Evaluate [1] and 7
[1] and 7
👉 [1] is a non-empty list
Non-empty list = Truthy ✅
For and:
If first value is truthy → return second value
👉 Result:
7
🔹 Step 3: Expression Now Becomes
[] or 0 or False or 7
🔹 Step 4: Evaluate or Left to Right
👉 First value:
[]
Empty list = Falsy ❌
Move ahead
👉 Second value:
0
0 = Falsy ❌
Move ahead
👉 Third value:
False
False = Falsy ❌
Move ahead
👉 Fourth value:
7
7 = Truthy ✅
For or:
Python returns first truthy value
👉 Result:
7
🔹 Step 5: Final Output
print(7)
👉 Output:
7
