Tuple Data Type

Tuple is a built-in immutable data type that is used to store a collection of data. It can be of the same or different data type. It’s best suitable for storing a data that cannot change since it’s immutable, unlike a list whose elements can be modified.

Creating a tuple

A tuple data type can be created using a comma separated-values placed within a parenthesis ().

Example:

creating a tuple

  # creating a tuple with different data type

  student_info = (“Ben”, 21, 8500.0)

  # Incorrect way of creating a tuple with one item
  number = (2)

  # Correct way of creating a tuple with one item
  price = (23,)

Note

When creating a tuple with one item, we put a comma after that item.

 

Other ways of creating a tuple

There are other ways of creating a tuple which we’ll mention.

using tuple() constructor

One of the built-in tuple() function is also used to create a tuple. It takes a sequence data type and constructs a tuple with it’s items. If no argument is provided then it will construct an empty tuple.

Example

using tuple() to create a tuple

  colors = ["red", "orange", "yellow"]

  tuple_colors = tuple(colors)
