Python - Basics

1. Installation: Before you start coding in Python, you need to install it on your computer. You can download Python from the official website (https://www.python.org/). Choose the latest version for your operating system. 2. Writing Your First Python Program: Once Python is installed, you can create and run Python programs using a code editor or an Integrated Development Environment (IDE). You can also use a simple text editor like Notepad or VS Code.
Open a text editor and create a file with a .py extension, for example, hello.py. Write the following code:

Save the file and open your terminal or command prompt. Navigate to the directory where you saved hello.py, and then run the program with the following command:

You should see the output: "Hello, World!". 3. Variables and Data Types:
In Python, you don't need to declare the data type explicitly; Python dynamically infers it. Here are some common data types:

4. Basic Operations:
Python supports various mathematical operations:

5. Control Flow:
Python uses indentation to define blocks of code. Here's how you can use if, elif, and else statements: ns:

6. Loops: Python supports for and while loops. Here's an example of a for loop:

7. Functions:
You can define functions in Python using the def keyword. Functions are blocks of reusable code:

8. Lists:
A list is a collection of items, and it is one of the most commonly used data structures in Python:

9. Dictionaries:
Dictionaries are collections of key-value pairs:

10. Modules and Libraries:
Python has a vast ecosystem of libraries that you can use to extend its functionality. For example, you can use the math library for mathematical operations:

This is just a basic introduction to Python. There's much more to explore, including object-oriented programming, file handling, error handling, and more. As you continue your Python journey, consider exploring these topics and working on small coding projects to reinforce your learning.
