Map two lists Python

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.
