Explanation:
๐น Step 1: Understand Operator Priority
In Python:
and → evaluated before → or
So Python first evaluates:
0 and [1]
{} and 7
Expression becomes:
[] or 0 or {} or "X"
๐น Step 2: Evaluate 0 and [1]
0 and [1]
๐ 0 is falsy ❌
For and:
If first value is falsy → return it immediately
So:
0 and [1] → 0
๐น Step 3: Evaluate {} and 7
{} and 7
๐ {} is empty dictionary
Empty dict = falsy ❌
For and:
Return first falsy value
So:
{} and 7 → {}
๐น Step 4: Expression Now Becomes
[] or 0 or {} or "X"
Now Python evaluates or from left to right.
๐น Step 5: Evaluate []
[]
๐ Empty list = falsy ❌
Move to next value
๐น Step 6: Evaluate 0
0
๐ 0 = falsy ❌
Move ahead
๐น Step 7: Evaluate {}
{}
๐ Empty dictionary = falsy ❌
Move ahead
๐น Step 8: Evaluate "X"
"X"
๐ Non-empty string = truthy ✅
For or:
Return FIRST truthy value
So result becomes:
"X"
๐น Step 9: Final Print
print("X")
๐ Final Output:
X
