In this tutorial, you’ll learn about Python closure, how to define a closure, and the reasons you should use it. What are Closures in Python? Like nested loops, we can also nest functions. That said, Python gives us the power to define functions within functions. Python Closures are these inner functions that are enclosed within the outer function. Closures can access variables present in the outer function scope. It can access these variables even after …
If you read the previous chapter, you know that iterators are objects that are regularly used with for loops. In other words, iterators are objects that implement the iteration protocol. A Python generator is a convenient way to implement an iterator. Instead of a class, a generator is a function which returns a value each time the yield keyword …

With the help of examples, you’ll learn about Object-Oriented Programming (OOP) in Python and its core concepts. Object Oriented Programming The program is easy to understand and efficient thanks to Object-Oriented Programming.The code can be reused because the class is sharable.Data abstraction keeps data safe and secure.Polymorphism allows programmers to build efficient code by allowing …
With the help of examples, you’ll learn how to manage exceptions in your Python program using try, except, and finally statements. Exceptions in Python When your program detects an error, Python raises a number of built-in exceptions (something in the program goes wrong).
