Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage. A tuple is a collection which is ordered and unchangeable .

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

Python Collections (Arrays) There are four collection data types in the Python programming language: List is a collection which is ordered and changeable. Allows duplicate members. Tuple is a collection which is ordered and unchangeable. Allows duplicate members.

x = tuple(("apple", "banana", "cherry")) tuple: Try it » x = range(6) range: Try it » x = dict(name="John", age=36) dict: Try it » x = set(("apple", "banana", "cherry")) set: Try it » x = frozenset(("apple", "banana", "cherry")) frozenset: Try it » x = bool(5) bool: Try it » x = bytes(5) bytes: Try it » x = bytearray(5) bytearray: Try it ...

Change Tuple Values. Once a tuple is created, you cannot change its values. Tuples are unchangeable, or immutable as it also is called. But there is a workaround. You can convert the tuple into a list, change the list, and convert the list back into a tuple.

Python has no command for declaring a variable. A variable is created the moment you first assign a value to it.

Note: Python does not have built-in support for Arrays, but Python Lists can be used instead. Arrays Note: This page shows you how to use LISTS as ARRAYS, however, to work with arrays in Python you will have to import a library, like the NumPy library .

A tuple is a typed array with a pre-defined length and types for each index. Tuples are great because they allow each element in the array to be a known type of value. To define a tuple, specify the type of each element in the array:

If you have a collection of values in a list, tuple etc. Python allows you to extract the values into variables. This is called unpacking.
