Convert List of Tuples to Dictionary in Python (3 Examples)

Hello! This tutorial will show you 3 ways to convert a list of tuples into a dictionary in the Python programming language.

First, though, here is an overview of this tutorial:

Let’s dive into the code!

Create List of Tuples

Tuples are used to store multiple items in one variable, and they are immutable, meaning they can’t be changed. To create the list of tuples that we will use in this tutorial, run the line of code below in your Python IDE:

my_tuples = [("Name", "John"),("Age", 25),("Occupation", "Analyst")]

Now we can convert the created my_tuples to a dictionary, which is a mutable object.

Example 1: Transform List of Tuples to Dictionary via dict() Function

In this first example, we will use the Python dict() function to convert the list of tuples into a dictionary:

my_dict = dict(my_tuples)
print(my_dict)
 
# {'Name': 'John', 'Age': 25, 'Occupation': 'Analyst'}

Example 2: Transform List of Tuples to Dictionary via Dictionary Comprehension

In this second example, we are going to use dictionary comprehension to convert the list of tuples into a dictionary:

my_dict = {i[0]: i[1] for i in my_tuples}
print(my_dict)
 
# {'Name': 'John', 'Age': 25, 'Occupation': 'Analyst'}

Example 3: Transform List of Tuples to Dictionary via for Loop

In this third and final example, we will use a for loop and the setdefault() method to convert the list of tuples into a dictionary:

my_dict = {}
for i,j in my_tuples:
  my_dict.setdefault(i,[]).append(j)
print(my_dict)
 
# {'Name': ['John'], 'Age': [25], 'Occupation': ['Analyst']}

So there you have it! We have demonstrated 3 simple ways to convert a list of tuples into a dictionary in Python.

I hope you found this helpful!
