Introduction to Python
Python is a high-level, interpreted programming language that was created by Guido van Rossum and first released in 1991. It is known for its simplicity, readability, and ease of learning. Python emphasizes code readability, which makes it an excellent choice for beginners. Python’s syntax allows developers to express concepts in fewer lines of code compared to other programming languages like C++ or Java.
Python is a general-purpose language, meaning it can be used for a wide variety of applications such as web development, data analysis, artificial intelligence, automation, scientific computing, and more. It supports multiple programming paradigms, including object-oriented, imperative, and functional programming.Python is a high-level, interpreted programming language that was created by Guido van Rossum and first released in 1991.

Python Installation and Setup
To start programming in Python, you need to install Python on your system. The official Python distribution is available at python.org. When installing Python, make sure to check the option that says “Add Python to PATH” during installation for easier access via the command line.
Once Python is installed, you can confirm it by typing python --version (or python3 --version for some systems) in your command line or terminal. This command will display the Python version installed on your system.
Additionally, Python comes with pip, the Python package installer, which can be used to install external libraries that are not part of the standard library. For example, you can install packages like numpy, pandas, and flask using pip install <package_name>.To start programming in Python, you need to install Python on your system.

Python Syntax
Python has a simple and readable syntax. It uses indentation to define blocks of code instead of braces {} or keywords like begin and end in other languages. This helps reduce clutter and makes the code visually appealing.
Case Sensitivity:
Python is case-sensitive, meaning variable and Variable would be treated as two different identifiers.
Comments:
Comments are essential for explaining code, and Python supports both single-line and multi-line comments:
- Single-line comment: Any text after a
#symbol is a comment.pythonCopy code# This is a single-line comment print("Hello, World!") # This prints a greeting - Multi-line comment: You can use triple quotes (
'''or""") for multi-line comments.pythonCopy code''' This is a multi-line comment that spans multiple lines. '''
