Please enter a non-negative integer.")...

Features of Python

Python’s syntax is easy to read and understand, making it good for beginners. The language emphasizes code readability, reducing the cost of program maintenance and development.It allows developers to express code in fewer lines of code than languages like C++ or Java. This leads to a more concise coding style.Python is an interpreted language, allowing for dynamic code execution without the need of a compilation step. This facilitates rapid development and testing. It is dynamically typed means that variable types are determined at runtime. Python supports OOPs principles, allowing developers to code using classes and objects.It comes with a number of standard library that includes modules and packages for a wide range of functionalities, including web development, data processing, networking, and file I/O....
