Python Coding Challenge - Question with Answer (ID -180326)

 

Code Explanation:

🔹 1. Creating a Tuple

t = (1, 2, 3, 4)

A tuple named t is created.

It contains 4 elements: 1, 2, 3, 4.

Tuples are immutable → you cannot change their values directly.

🔹 2. Starting a Loop

for i in t:

This is a for loop that iterates over each element of the tuple.

On each iteration, i takes one value from t.

Iteration steps:

1st → i = 1

2nd → i = 2

3rd → i = 3

4th → i = 4

🔹 3. Modifying the Loop Variable

i += 10

This adds 10 to the current value of i.

But important point:

It does NOT change the tuple

It only changes the temporary variable i

So values become:

1 → 11

2 → 12

3 → 13

4 → 14

But these values are not stored anywhere.

🔹 4. Printing the Tuple

print(t)

This prints the original tuple.

Since tuples are immutable and unchanged, output remains the same.

✅ Final Output

(1, 2, 3, 4)
