Collections
Collections are mainly used to store multiple data together. By default, Python provides mainly 4 types of collections which are mainly used in the programming world. They are as follows:

Dictionary


Dictionaries in Python
Python dictionaries are unordered, changeable and indexed collection of items which consists of key value pair.
Python dictionaries are very much handy when the key is known and the value has to be retrieved. We can also access all the keys and values in an iterable format or can iterate over the key-value pairs altogether.
Example = { 'Name': ‘John Doe', 'Age': 23 }
