UNIT 1: INTRODUCTION TO PYTHON
Learning Objectives
Understand Python, its history, features, applications, installation process, IDEs, and execution
process.
1. Introduction to Programming
Programming is the process of giving instructions to a computer. Computers understand machine
language, so programmers use languages such as Python to communicate with them. Example:
adding two numbers and displaying the result.
2. What is Python?
Python is a high-level, interpreted, general-purpose programming language. It is easy to learn and
supports procedural, object-oriented, and functional programming styles.
3. History of Python
Python was developed by Guido van Rossum in 1989 and officially released in 1991. Python 3.0
was released in 2008 and remains the foundation of modern Python development.
4. Features of Python
Simple syntax, interpreted execution, platform independence, open source nature, large standard
library, dynamic typing, and object-oriented support.
5. Applications of Python
Used in Web Development, Artificial Intelligence, Machine Learning, Data Science, Automation,
Cyber Security, and Software Development.
6. Installing Python
Download Python, install it, enable 'Add Python to PATH', and verify installation using python
--version.
7. Python IDEs
Popular IDEs include IDLE, Visual Studio Code, PyCharm, and Jupyter Notebook.
8. First Python Program
Program:
print('Hello World')
Output:
Hello World
The print() function displays text on the screen.
9. Python Execution Process
