Python Coding Challenge - Question with Answer (ID -010526)

Python Developer May 01, 2026 Python Quiz No comments

Explanation:

🔹 Step 1: Create Tuple

x = (1,[2,3])

x is a tuple (immutable)

Inside tuple:

1 → integer

[2,3] → mutable list

🔹 Step 2: Apply += Operation

x[1] += [4]

👉 This works in two steps internally:

🔸 Step 2.1: Modify List (In-place)

[2,3] += [4] → [2,3,4]

List is mutable → gets updated ✅

🔸 Step 2.2: Try to Reassign

x[1] = [2,3,4]

Tuple is immutable ❌

Reassignment is not allowed

🔹 Step 3: Error Occurs

Python throws:

TypeError

🔹 Step 4: Print Not Executed

print(x)

This line never runs because program stops at error

⚡ Final Output

Error
