A tuple is a collection of data that is ordered and unchangeable. Tuples are written with round brackets and can have items with the same value².

To access tuple items, you can use the index number inside square brackets. The index starts from 0 for the first item, and can be negative to count from the end¹.

For example, to print the second item in a tuple, you can write:

To print the last item in a tuple, you can write:

You can also use a range of indexes to access a subset of the tuple. The range is specified by a colon (:), and the return value will be a new tuple with the specified items¹.

For example, to print the third, fourth, and fifth items in a tuple, you can write:

Note that the start index is included, but the end index is not.

You can also leave out the start or the end index to specify the beginning or the end of the tuple¹.

For example, to print the items from the beginning to "kiwi" (not included), you can write:

To print the items from "cherry" (included) to the end, you can write:

To check if an item is present in a tuple, you can use the in keyword¹.

For example, to check if "apple" is in the tuple, you can write:
