Setting Up Development Environment

Prepare your tools and environment for programming

Setting Up Your Development Environment

Before writing your first Python program, you need to set up your development environment — the tools that will accompany you throughout this course.

What is a Development Environment?

A development environment is the combination of tools and software you use to write, test, and run your programs. Think of it as your personal digital workshop.

Essential Tools

1. Code Editor or IDE

You need a place to write your code. Popular options for Python include:

• Visual Studio Code — Free, lightweight, and widely used
• PyCharm — Powerful IDE built specifically for Python (free Community edition available)
• IDLE — Comes bundled with Python, great for absolute beginners
• Thonny — Simple and beginner-friendly, ideal for first-timers

2. Python Interpreter

Unlike C++, Python does not need a separate compiler — it uses an interpreter that reads and executes your code directly.

• CPython — The standard and most widely used Python interpreter
• PyPy — A faster alternative, often used in competitive programming for speed

3. Terminal or Command Prompt

You will use this to run your Python scripts and execute commands.

Installation Steps

For Windows:

1. Go to python.org and download the latest Python version
2. Run the installer — make sure to check "Add Python to PATH" before clicking Install
3. Download and install a code editor (e.g., Visual Studio Code)
4. Verify your installation by opening Command Prompt and typing:

For macOS:

1. Open Terminal and install Homebrew if you don't have it:

2. Install Python via Homebrew:

3. Verify with:

For Linux:

1. Python is usually pre-installed. Check with:

2. If not installed:

3. Install a code editor of your choice

Your First Test

Once everything is set up, create a file called test.py and write the following:

Run it from your terminal with:

If you see Environment setup successful! printed — you are ready to go!
