What Is the Python Data Type With Parentheses?


Larry Thompson

Python is a versatile programming language that offers a wide range of data types to store and manipulate different kinds of information. One such data type with parentheses is the tuple. In this article, we will explore what tuples are, how they differ from other data types, and how to use them effectively in your Python programs.

What is a Tuple?

A tuple is an ordered collection of elements enclosed in parentheses (). Unlike lists, which use square brackets [], tuples are immutable, meaning their values cannot be changed after they are created. This immutability makes tuples useful for representing fixed collections of items that should not be modified.

Tuples can contain elements of different data types, such as numbers, strings, or even other tuples. The elements within a tuple are separated by commas. Let’s take a look at an example:

<u># Creating a tuple</u>
my_tuple = (1, 'hello', (2.3, 4.5), 'world')

The above code creates a tuple named my_tuple with four elements – an integer 1, the string ‘hello’, another tuple containing two floating-point numbers (2.3 and 4.5), and finally the string ‘world’. When we print my_tuple, we will see the entire tuple displayed as output.

Accessing Tuple Elements

To access individual elements within a tuple, you can use indexing. Indexing starts from 0 for the first element and goes up to n-1 for the last element (where n is the number of elements in the tuple). Let’s see some examples:

<u># Accessing tuple elements</u>
print(my_tuple[0])  <u># Output: 1</u>
print(my_tuple[1])  <u># Output: hello</u>
print(my_tuple[2])  <u># Output: (2.5)</u>
print(my_tuple[-1]) <u># Output: world</u>

In the above code, we access the elements of my_tuple using square brackets with the desired index. We can also use negative indexing to access elements from the end of the tuple.

Modifying Tuples

As mentioned earlier, tuples are immutable, so you cannot change individual elements once a tuple is created. However, you can perform operations that result in a new tuple. Let’s explore some common operations:

Concatenating Tuples

You can concatenate two or more tuples using the ‘+’ operator. The result is a new tuple containing all the elements from both tuples.

<u># Concatenating tuples</u>
tuple_1 = (1, 2)
tuple_2 = ('a', 'b')
concatenated_tuple = tuple_1 + tuple_2
print(concatenated_tuple) <u># Output: (1, 2, 'a', 'b')</u>

Duplicating Tuples

You can create duplicate tuples by multiplying them with an integer. The resulting tuple will contain multiple copies of the original tuple.

<u># Duplicating tuples</u>
original_tuple = (1, 'hello')
duplicated_tuple = original_tuple * 3
print(duplicated_tuple) <u># Output: (1, 'hello', 1, 'hello', 1, 'hello')</u>

Iterating Over Tuples

You can iterate over the elements of a tuple using a for loop. This allows you to perform certain operations on each element of the tuple.

<u># Iterating over a tuple</u>
my_tuple = (1, 2, 3, 4)
for element in my_tuple:

The above code prints each element of my_tuple on a new line.

Tuples vs. Lists

Tuples and lists are both used to store collections of items in Python, but they have some key differences:

  • Tuple: Immutable – cannot be modified once created.
  • List: Mutable – can be modified after creation.
  • Tuple: Use parentheses () for notation.
  • List: Use square brackets [] for notation.
  • Tuple: Faster to access elements than lists.
  • List: Slower to access elements than tuples.

In general, tuples are preferred when you have a fixed collection of items that should not be modified. Lists, on the other hand, are more flexible and allow for dynamic changes.


In this article, we explored the tuple data type in Python. We learned that tuples are ordered collections of elements enclosed in parentheses.

Tuples are immutable, meaning their values cannot be changed after creation. We also covered how to access tuple elements using indexing, perform operations like concatenation and duplication, and iterate over tuples using loops. Finally, we compared tuples to lists and discussed their use cases.

Tuples can be a powerful tool in your Python programming arsenal, offering a reliable way to store fixed collections of information. By understanding how to create and manipulate tuples effectively, you can enhance your ability to write efficient and organized code.
