Python is a versatile and beginner-friendly programming language. It features a clear and readable syntax, making it easy to learn and understand. Functions are essential building blocks in Python that allow you to break down complex tasks into smaller, reusable modules. They improve code organization, readability, and maintainability, enhancing productivity and facilitating code reuse in various applications. In Python, variables are used to store and manipulate data. A variable is essentially a named location in memory that holds a value. Unlike some other programming languages, Python does not require explicit declaration of variables. You can assign a value to a variable using the assignment operator (=).
For example, x = 5 assigns the value 5 to the variable x.
What is Python?
Python is an interpreted, high-level, general-purpose programming language. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming. Python is often described as a "batteries included" language due to its comprehensive standard library.

Uses of Python.
Python can be used to develop different applications like web applications, graphic user interface based applications, software development application, scientific and numeric applications, network programming, Games and 3D applications and other business applications.
1) Python can be used to develop prototypes, and quickly because it is so easy to work with and read.
2) Most automation, data mining, and big data platforms rely on Python. This is because it is the ideal language to work with for general purpose tasks.
3) Python allows for a more productive coding environment than massive languages like C# and Java. Experienced coders tend to stay more organized and productive when working with Python, as well.
4) Python is easy to read, even if you're not a skilled programmer. Anyone can begin working with the language, all it takes is a bit of patience and a lot of practice. Plus, this makes it an ideal candidate for use among multi-programmer and large development teams.
5) Python powers Django, a complete and open source web application framework. Frameworks - like Ruby on Rails - can be used to simplify the development process.

We will primarily be focusing only on Strings and Integers.
Variables
Variables are used for storing data values. A variable is created the moment you first assign a value to it.
Comments can be used to explain Python code. Comments can be used to make the code more readable. Comments can be used to prevent execution when testing code.
