Python Basics — IDE & Tools

IDE & Tools

An IDE (Integrated Development Environment) is a special text editor designed for writing code. It gives you features like syntax highlighting, auto-completion, error detection, and debugging.

You can write Python in Notepad or TextEdit, but an IDE makes you significantly more productive.

Visual Studio Code by Microsoft is the most popular code editor in the world. It’s free, fast, and has excellent Python support.

Setup

  1. Download from code.visualstudio.com
  2. Install and open VS Code
  3. Install the Python extension by Microsoft (click the Extensions icon → search “Python” → Install)
  4. Open a folder for your Python projects
  5. Create a .py file and start coding

Key Features

Feature What It Does
IntelliSense Auto-completion and suggestions as you type
Linting Highlights errors and style issues in real-time
Debugging Step through code line by line
Integrated Terminal Run Python scripts without leaving the editor
Git Integration Built-in version control
Extensions Thousands of extensions for extra features

Useful VS Code Shortcuts

Shortcut (Mac) Shortcut (Win/Linux) Action
Cmd + Shift + P Ctrl + Shift + P Command Palette
Cmd + / Ctrl + / Toggle comment
Cmd + S Ctrl + S Save file
Cmd + Ctrl + Toggle terminal
F5 F5 Run/Debug

PyCharm Community Edition

PyCharm by JetBrains is a full-featured Python IDE. The Community Edition is free and great for Python development.

When to Consider PyCharm

  • You’re working on larger projects
  • You want a more “batteries included” IDE
  • You need advanced refactoring tools
  • You’re building Django or Flask applications

Setup

  1. Download from jetbrains.com/pycharm
  2. Choose “Community Edition” (free)
  3. Install and create a new Python project
  4. PyCharm will automatically detect your Python interpreter

Jupyter Notebook

Jupyter Notebook is an interactive Python environment that runs in your web browser. It’s perfect for data exploration, learning, and documentation.

Setup

pip3 install notebook
jupyter notebook

This opens a browser tab where you can create “notebooks” — documents with code cells that you can run one at a time.

When to Use Jupyter

  • Learning Python (great for experimenting)
  • Data analysis and visualization
  • Creating tutorials and documentation
  • Machine learning experiments

When NOT to Use Jupyter

  • Building applications (use VS Code or PyCharm instead)
  • Large codebases with multiple files
  • Production code

IDLE (Built-In)

Python comes with IDLE — a basic IDE that’s already installed when you install Python.

Starting IDLE

python3 -m idlelib

IDLE is fine for quick experiments but lacks the features of VS Code or PyCharm. It’s useful when you need a quick scripting environment and nothing else is available.

Online Editors

No installation needed — write Python directly in your browser:

Editor URL Best For
Replit replit.com Quick experiments, collaboration
Google Colab colab.google Data science, ML, free GPU
Python.org Shell python.org/shell Quick REPL access
Programiz programiz.com Beginner practice

Our Recommendation

For this tutorial, we recommend VS Code with the Python extension. It’s:

  • Free and cross-platform
  • Lightweight but powerful
  • The most popular editor among Python developers
  • Great for beginners AND professionals

As you progress, you might also use Jupyter for data-related work and PyCharm for larger projects.

Summary

  • VS Code is the recommended editor for beginners (free, powerful, popular)
  • PyCharm CE is great for larger projects and advanced features
  • Jupyter Notebook is ideal for learning, data science, and experimentation
  • IDLE comes built-in with Python for quick scripting
  • Online editors let you code without installing anything
  • Install the Python extension in VS Code for the best experience
