In this example, you will learn to convert two lists into a dictionary.
Table of Contents
Example 1: Using zip and dict methods
index = [1, 2, 3]
languages = ['python', 'c', 'c++']
dictionary = dict(zip(index, languages))
print(dictionary)
Output
{1: 'python', 2: 'c', 3: 'c++'}
We have two lists: index and languages. They are first zipped and then converted into a dictionary.
-
The
zip()
function takes iterables (can be zero or more), aggregates them in a tuple, and returns it. -
Likewise,
dict()
gives the dictionary.
Example 2: Using list comprehension
index = [1, 2, 3]
languages = ['python', 'c', 'c++']
dictionary = {k: v for k, v in zip(index, languages)}
print(dictionary)
Output
{1: 'python', 2: 'c', 3: 'c++'}
This example is similar to Example 1; the only difference is that list comprehension is being used for first zipping and then { } for converting into a dictionary.
