# Python Tuples

Tuples are used to store multiple items in a single variable. A tuple is a collection which is ordered and unchangeable.

## Creating a Tuple

Tuples are written with round brackets.

```python
thistuple = ("apple", "banana", "cherry")
print(thistuple)
```

## Access Tuple Items

You can access tuple items by referring to the index number, inside square brackets:

```python
thistuple = ("apple", "banana", "cherry")
print(thistuple[1]) # Output: banana
```

## Update Tuples

Tuples are unchangeable, meaning that you cannot change, add, or remove items once the tuple is created.

However, there is a workaround. You can convert the tuple into a list, change the list, and convert the list back into a tuple.

```python
x = ("apple", "banana", "cherry")
y = list(x)
y[1] = "kiwi"
x = tuple(y)

print(x)
```

## Unpacking a Tuple

When we create a tuple, we normally assign values to it. This is called "packing" a tuple. But, in Python, we are also allowed to extract the values back into variables. This is called "unpacking".

```python
fruits = ("apple", "banana", "cherry")

(green, yellow, red) = fruits

print(green)
print(yellow)
print(red)
```

## Loop Through a Tuple

You can loop through the tuple items by using a `for` loop.

```python
thistuple = ("apple", "banana", "cherry")
for x in thistuple:
  print(x)
```

## Tuple Methods

Python has two built-in methods that you can use on tuples.

*   `count()`: Returns the number of times a specified value occurs in a tuple.
*   `index()`: Searches the tuple for a specified value and returns the position of where it was found.
