Introduction:

Computer programming is a well defined process of writing, testing, debugging, troubleshooting and maintaining programs. To write any computer program it is needed to understand the problem then try to solve it in logical manner.

Python is a programming language. It is very popular because of its features and advantages over other similar programming languages.

Features of Python language:

Python is:

• Simple
• Easy to learn
• Easy to read 
• Easy to understand
• Easy to maintain
• Run on any platform
• Large built-in library
• Lesser code than C++/Java
• Dynamically and strongly typed language
• Uses Indentation
• Can be easily Integrated
• Portable
• Extendable
• Connectivity with all major databases
• GUI (Graphical User Interface) programming
• Scalable

🐍 Introduction to Python Programming

Python is one of the most popular and beginner-friendly programming languages in the world today. Whether you're building websites, analyzing data, automating tasks, or exploring artificial intelligence, Python has something to offer.

🕰️ A Brief History of Python

Python was created by Guido van Rossum and first released in 1991. The language was designed with a strong emphasis on readability, simplicity, and clean syntax—all of which make it a great choice for beginners.

🧠 Fun Fact: The name "Python" doesn’t come from the snake—it was actually inspired by the British comedy group Monty Python!

Since its release, Python has grown steadily, and today it powers everything from simple scripts to complex machine learning systems.

Python Programming Modes: 

Python programs can be run on any of the two modes:

1. Interactive Mode
2. Script Mode

1. Interactive mode: It allows to interacts with operating system. We can get immediate output. It reads and interprets single line at a time and gives the output of the statement. It is like command prompt in windows.
          >>>           (this shows we are in interactive mode )

        *want to know more about python interactive mode view our tutorial Python Interactive Mode



2. Script mode: This mode writes python program in a file , then use the interpreter to execute the content of the file. We can use any editor like notepad to write the script or program.
