A dictionary is an unordered collection of key-value pairs. Each entry has a key and value. A dictionary can be considered as a list with special index.

The keys must be unique and immutable. So we can use strings, numbers (int or float), or tuples as keys. Values can be of any type.

In this article, we will focus on dictionary comprehension which is a method to create dictionaries using iterables. The logic is the same as list comprehension but the syntax is different due to the structure of dictionaries.

In order to see the similarity between a list and dictionary comprehension, I will create both a list and dictionary comprehension in the first two examples.
