Set is an unordered collection data type that iterable, mutable and has no duplicate element. Set is represented by {}. Set is highly optimized method for checking whether a specific element is present in the set. Sets are created by placing all the items or elements inside curly brackets {...
Tokens in Python are the smallest unit in the program that represents a keyword, operator, identifier, or literal. Know the types of tokens and tokenizing elements.

In this case, you use@add_messagesto decorategreet(). This adds new functionality to the decorated function. Now when you callgreet(), instead of just printingHello, World!, your function prints two new messages. The use cases for Python decorators are varied. Here are some of them: ...

We have seenbeforethat there are differences between mutable and immutable types in Python. Built-in immutable types have always a hash method, while mutable types don't. However, this leaves outside custom defined classes. By default, all instances of custom classes will have a hash value def...
