Python Generators
Python Generators Table Of Contents: What Is Generator In Python? How To Create A Generator? Examples Of Generators. Advantages Of Using Generators. (1) What Is Generator In Python? The problem with iterators like list, set, tuple and dictionary is that they are too slow to fetch values from them. To solve this problem we have ‘Generators’ in Python. Generators help us to retrieve elements from the iterators like list, set, tuple and dictionary much faster ways, as compared to traditional using a ‘for’ loop to iterate.

Python Decorators
Python Decorators Table Of Contents: What Are Decorators In Python? Examples Of Decorators. Using Multiple Decorators. (1) What Are Decorators In Python? Decorators are just the usual methods used to add extra functionalities to an existing method. Python provides us with a way to add some extra functionality to an existing method, by using ‘Decorators’. Decorators actually don’t modify the codes inside the function, otherwise, it will cause serious security issues. Instead, it extends the function by adding some extra lines to it. Imagine a situation where you are using the methods from another file, that you don’t have access
