Detailed explanation-1: -Keys are unique within a dictionary while values may not be. The values of a dictionary can be of any type, but the keys must be of an immutable data type such as strings, numbers, or tuples.
Detailed explanation-2: -Get value from dictionary with dict[key] ( KeyError for non-existent keys) In Python, you can get the value from a dictionary by specifying the key like dict[key] . In this case, KeyError is raised if the key does not exist.
Detailed explanation-3: -A Python dictionary is a collection of key-value pairs where each key is associated with a value. A value in the key-value pair can be a number, a string, a list, a tuple, or even another dictionary. In fact, you can use a value of any valid type in Python as the value in the key-value pair.
