How to install Python Visual?

Published in Python Development Environment 6 mins read

To effectively set up a visual development environment for Python, you first need to install Python itself, and then integrate it with a powerful Integrated Development Environment (IDE) like Visual Studio Code or PyCharm. This allows you to write, debug, and run your Python code with visual aids and advanced features.

Getting Started: Installing Python

Installing Python is the foundational step for any visual development setup. You have two primary options for Windows users, with the official installer being the most common choice across all operating systems.

Option 1: Official Python Installer (Recommended)

This method provides the full Python installation and is recommended for most users.

  1. Visit the official Python website: Open your web browser and navigate to python.org.
  2. Download the latest version: Click the prominent "Download Python" button, which typically appears first on the page, to download the installer for your operating system (Windows, macOS, or Linux).
  3. Run the installer: Locate the downloaded installer file (e.g., python-X.Y.Z.exe for Windows) and double-click to run it.
  4. Add Python to PATH: Crucially, on the first screen of the installer, check the box that says "Add Python X.Y to PATH" (where X.Y is the version number). This step is vital as it allows you to run Python commands directly from your command line or terminal.
  5. Complete installation: Choose "Install Now" for a standard installation or "Customize installation" if you need to select specific features or change the installation directory. Follow the remaining prompts to finish the installation.

Option 2: Microsoft Store (Windows Users without Admin Access)

If you are on a Windows machine and do not have administrative privileges to install software system-wide, the Microsoft Store offers a convenient alternative.

  1. Open the Microsoft Store: Click the Start button and search for "Microsoft Store."
  2. Search for Python: In the Microsoft Store, use the search bar to find "Python."
  3. Select a supported version: Choose a supported Python version (e.g., "Python 3.10") offered by the Python Software Foundation.
  4. Install Python: Click "Get" or "Install" to download and install Python. This method automatically manages the PATH environment variable for you, making it immediately accessible.

Verifying Your Python Installation

After installing Python, it's good practice to confirm that it's correctly set up and accessible.

  1. Open your command line:
    • Windows: Search for "Command Prompt" or "PowerShell" in the Start menu.
    • macOS/Linux: Open "Terminal."
  2. Check Python version: Type python --version or python3 --version and press Enter.
  3. Confirm output: You should see the installed Python version displayed (e.g., Python 3.10.12). If you get an error like 'python' is not recognized..., it usually means Python wasn't added to your system's PATH correctly, or you might need to restart your terminal.

Choosing and Installing a Visual Development Environment (IDE)

While Python comes with a basic interactive shell and IDLE, an IDE significantly enhances your development experience with features like intelligent code completion, debugging tools, and project management.

Visual Studio Code (VS Code) - Highly Recommended

VS Code is a free, lightweight, yet powerful code editor developed by Microsoft, offering excellent support for Python through extensions.

  1. Download and Install VS Code:
    • Visit the official VS Code website: code.visualstudio.com.
    • Download the installer for your operating system.
    • Run the installer and follow the instructions. During installation, consider checking options like "Add 'Open with Code' action to Windows Explorer context menu" for quick file access.
  2. Install the Python Extension:
    • Open VS Code.
    • Go to the Extensions view by clicking the Extensions icon on the sidebar (or pressing Ctrl+Shift+X).
    • In the search bar, type "Python" and look for the official "Python" extension by Microsoft.
    • Click "Install." This extension provides linting, debugging, IntelliSense, and more.
  3. Select Your Python Interpreter:
    • Open any Python file (.py) in VS Code.
    • VS Code will usually detect your installed Python versions. If prompted, select the Python installation you made earlier.
    • Alternatively, click the Python version displayed in the bottom-left status bar (e.g., "Python 3.10.12 64-bit") or press Ctrl+Shift+P, type "Python: Select Interpreter," and choose your desired Python installation.
  4. Running Python Code in VS Code:
    • Create a new file, save it as hello.py, and add some code, for example:
      message = "Hello, Visual Python Development!"
print(message)
    • You can run this file by clicking the "Run Python File" play button in the top-right corner of the editor, or by right-clicking anywhere in the editor and selecting "Run Python File in Terminal."

PyCharm - Professional Python IDE

PyCharm, developed by JetBrains, is a dedicated Python IDE known for its robust features, especially for larger projects and professional development.

  1. Download PyCharm:
    • Visit the official PyCharm website: jetbrains.com/pycharm.
    • Download the Community Edition, which is free and open-source, offering most features needed for general Python development.
  2. Install PyCharm:
    • Run the downloaded installer and follow the on-screen instructions.
  3. Create a New Project:
    • Open PyCharm.
    • Click "New Project" and configure your project details. PyCharm is excellent at automatically detecting your installed Python interpreters and can even set up virtual environments for you.

IDLE - Python's Built-in Development Environment

IDLE (Integrated Development and Learning Environment) is a simple IDE that comes bundled with standard Python installations. It's suitable for beginners and for quickly testing small scripts.

  1. Access IDLE: Search for "IDLE" in your operating system's applications menu (e.g., Start menu on Windows, Applications folder on macOS).
  2. Use the interactive shell: When opened, IDLE starts with an interactive shell where you can type Python commands directly.
  3. Create new files: You can also go to File > New File to open a new editor window for writing and saving Python scripts (.py files).

Comparing Popular Python IDEs

Target Audience Developers across various languages, web dev Python developers (professional & learners) Beginners, simple tasks

Practical Tips for a Smooth Visual Python Setup

  • Keep Python Updated: Regularly check python.org for the latest stable Python versions to benefit from new features and security updates.
  • Utilize Virtual Environments: For each of your Python projects, use venv (built-in) or conda to create isolated virtual environments. This keeps project dependencies separate and prevents conflicts. You can create one with python -m venv myenv in your project directory.
  • Configure Linting and Formatting: Install and configure extensions like Pylance (for VS Code) or tools like Black to maintain consistent code style and catch potential errors early.
  • Master the Debugger: Learn to use the debugging features in your chosen IDE. Setting breakpoints and stepping through your code is an invaluable skill for finding and fixing issues.
