✳️ About the video
========================
In this video we will learn python dictionary, create python dictionary, accessing elements from dictionary, changing and adding dictionary elements, removing elemets from dictionary.

Python Dictionary:
A Python dictionary is a mutable, unordered collection of key-value pairs, where each unique key is associated with a value.
Create Python Dictionary: A Python dictionary can be created by placing a comma-separated list of key-value pairs within curly braces, e.g., my_dict = {"key1": "value1", "key2": "value2"}.

Accessing Elements from Dictionary: Elements in a dictionary can be accessed by their key name, e.g., my_dict["key1"] will return "value1".
Changing and Adding Dictionary Elements: Dictionary elements can be added or changed using the assignment operator, e.g., my_dict["key3"] = "value3" adds a new key-value pair, and my_dict["key1"] = "newvalue" modifies an existing one.
Removing Elements from Dictionary: Elements can be removed from a dictionary using the del statement, e.g., del my_dict["key1"] removes the key-value pair with key "key1".
