The dictionary is an unordered list of key:value pairs separated by commas within curly brackets. When the key is known, dictionaries are optimised to retrieve values.
In computer science, a dictionary or association list is a data structure that maps keys to values. The keys are usually unique and the order is arbitrary. Dictionaries provide a way of storing information about objects in an efficient manner by denoting object information as key-value pairs.
Dictionaries are an important data structure in Python programming. They can be created in two ways: one is with the curly brackets and the other is with the dict command. A dictionary is a collection of keys and values that has a unique key for every value. Dictionaries are useful because they allow for quick lookups of information using their keys.
Python dictionaries are a built-in type for storing data. They use the syntax dict = {} and can contain key-value pairs, unlike a list which is ordered and has no keys. They can be accessed with the syntax dict[key] which returns the value of the specified key from the dictionary.
Python dictionaries are a data structure that maps keys to values. These can be created with certain keywords, or by using the dict() function. Dictionaries are able to store any type of object. Using this, programmers have the power to create complex, yet organized structures that can otherwise be time-consuming and difficult to maintain in other languages.

His way of teaching, explaining, and giving examples so that we can understand the concept is good but he don't give the complete information in some topics like in math module he told only about 4 modules but when I asked about it from chat GPT, it have me 22 modules so I recommend you to get the same information on the topic from other sources too so that you cal get full information as well.
