Python is a clear and powerful object-oriented programming language that is easy to test code snippets interactively. It supports basic data types like numbers, strings, lists, and dictionaries. Python can be installed on Windows by downloading from python.org or is pre-installed on Linux. Python scripts are run by saving files with a .py extension and running them using the shell on Windows or terminal on Linux. Python uses control statements like if/else, for and while loops, and break and continue statements.

3. Introduction to Python
o Python is a clear and powerful object-oriented programming language.
o Python's interactive mode makes it easy to test short snippets of code. There's also a
bundled development environment called IDLE
o A variety of basic data types are available: numbers (floating point, complex, and
unlimited-length long integers), strings (both ASCII and Unicode), lists, and
dictionaries.

4. Installation of Python on Windows / Linux
1. For Windows
• Download Python from www.python.org
2. For Linux
• Python is already install on Linux when
Operating System is getting installed

5. Running Python Scripts
• Generally programmers write stand alone scripts
• Save the file with a ".py" extension
1. On Windows
• Run the program using on Shell using “F5” Key
2. On Linux
• Run the Program using ‘terminal’ with
Syntax:- python filename.py
