How to Unzip List of Tuples in Python

To unzip a list of tuples in Python, you can use one of the following ways. Using zip() and * operatorUsing List Comprehension.

Python zip() method returns the zip object, which is an iterator of tuples. The zip() method creates an iterator that will aggregate items from two or more iterables.

How to Unzip List of Tuples in Python

To unzip a list of tuples means it returns the new list of tuples where each tuple consists of the identical items from each original tuple.

To unzip a list of tuples in Python, you can use one of the following ways.

  1. Using zip() and * operator
  2. Using List Comprehension

#1: Using zip() and * operator

The * operator unzips the tuples into independent lists. Combination with the Python zip() method, it will help us to unzip the list of tuples.


data_list = [('Harry', 17), ('Hermione', 17), ('Ginny', 16)]

print('Original List: ', str(data_list))

unzipped_list = list(zip(*data_list))

print('Unzipped list', unzipped_list)
Original List:  [('Harry', 17), ('Hermione', 17), ('Ginny', 16)]
Unzipped list [('Harry', 'Hermione', 'Ginny'), (17, 17, 16)]

In this example, we have defined a list of three tuples that we need to unzip, and then we print the list. In the next step, we have used the combination of zip() and * operator to unzip the tuple and make an iterator, and then we convert that iterator into a list using the list() method.

By inserting * before the list’s name, we can iterate through each item in the list and unzip the tuple.

Magic methods can be identified with their names which start with __ and ends with __ like __init__, __call__, __str__ etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).
