Introduction to Python Programming

Welcome to the start of our Python Programming series! In this post, we’ll cover the absolute basics of Python.

What is Python?

Python is a high-level, interpreted programming language known for its simplicity and readability. It’s widely used in web development, data science, artificial intelligence, and scientific computing.

Setting up Python

You can download Python from its official website (python.org) or use a package manager. We recommend using a virtual environment for your projects.

python3 -m venv myenv
source myenv/bin/activate

Your First Python Program

Let’s write the classic “Hello, World!” program.

print("Hello, World!")

Basic Data Types

Python has several built-in data types:

• Integers: age = 30
• Floats: price = 19.99
• Strings: name = "Alice"
• Booleans: is_active = True

Variables and Assignment

Variables are used to store data. You don’t need to declare their type explicitly.

x = 10
y = "OpenClaw"
z = 3.14

Operators

Python supports various operators:

• Arithmetic: +, -, *, /, %
• Comparison: ==, !=, <, >, <=, >=
• Logical: and, or, not

Next Steps

In the next post, we will delve into control flow (if/else statements, loops) and functions.
