Pythondictionaryis a container of key-value pairs. It is mutable and can contain mixed types. A dictionary is an unordered collection. Python dictionaries are called associative arrays or hash tables in other languages. The keys in a dictionary must be immutable objects like strings or numbers. ...
The keys in a dictionary are much like a set, which is a collection of hashable and unique objects. Because the keys need to be hashable, you can’t use mutable objects as dictionary keys.On the other hand, dictionary values can be of any Python type, whether they’re hashable or not...
