Data structures in python | dictionary | for beginners
In Python, dictionaries are mutable data structures that allow you to store key-value pairs. Dictionary can be created using the dict() constructor or curly braces’ {}’. Once you have created a dictionary, you can add, remove, or update elements using the methods (), (), and ().
The `()` method is used to change an element in a dictionary. This method takes a key and a value as arguments and assigns the value to the key. It will be added if the key does not exist in the dictionary.
