Question
![**Problem Statement:**
What is the output of the following code?
```python
x = ("apple", "banana", "cherry")
y = list(x)
y[1] = "kiwi"
x = tuple(y)
print(x)
```
**Explanation:**
1. **Tuple Creation:**
The initial tuple `x` is defined as `("apple", "banana", "cherry")`.
2. **Conversion to List:**
The tuple `x` is converted to a list `y` using the `list()` function. Now, `y` is `["apple", "banana", "cherry"]`.
3. **Modification:**
The second element of the list `y` (index 1) is changed from `"banana"` to `"kiwi"`. So, `y` becomes `["apple", "kiwi", "cherry"]`.
4. **Conversion Back to Tuple:**
The modified list `y` is then converted back to a tuple `x` using the `tuple()` function. So now, `x` is `("apple", "kiwi", "cherry")`.
5. **Output:**
The `print(x)` statement outputs the modified tuple:
`('apple', 'kiwi', 'cherry')`
**Key Concepts:**
- Tuples are immutable, meaning their elements cannot be changed directly. To modify a tuple, it must first be converted to a list.
- Lists are mutable, so elements can be updated, removed, or added.
- After modification, lists can be converted back to tuples if immutability is desired again.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa2fae0d2-f8de-4d86-b278-3d843b434350%2F631aafc5-f58e-42ae-bf08-ebdd9e72589f%2F8rxw70m_processed.jpeg&w=3840&q=75)
