Setting Up Your Python Development Environment

Posted on by Khalil Hijazi

To start writing and running Python code efficiently, it’s important to set up a proper development environment. In this blog post, we will guide you through the process of setting up your Python development environment step by step.

Choosing an Integrated Development Environment (IDE)

An Integrated Development Environment (IDE) is a software application that provides a comprehensive set of tools for writing, debugging, and testing code. While Python can be written using a simple text editor, using an IDE can greatly enhance your development experience. Here are a few popular options:

  • PyCharm: Developed by JetBrains, PyCharm is a powerful and feature-rich IDE specifically designed for Python development. It offers code completion, debugging tools, and integrations with version control systems.
  • Visual Studio Code: A lightweight and extensible code editor, Visual Studio Code (VS Code) has gained popularity among developers. It supports Python through various extensions and offers features like IntelliSense, debugging, and integrated terminal.
  • Jupyter Notebook: Jupyter Notebook provides an interactive environment for Python programming. It allows you to create and share documents that combine code, visualizations, and narrative text. It’s particularly useful for data analysis and experimentation.

Feel free to explore these options and choose the one that best suits your needs. For the purpose of this tutorial, we will use Visual Studio Code.

Installing Visual Studio Code and the Python Extension

To set up Visual Studio Code for Python development, follow these steps:

  1. Download Visual Studio Code from the official website: code.visualstudio.com.
  2. Run the installer and follow the on-screen instructions to complete the installation.
  3. Once installed, open Visual Studio Code.
  4. Install the Python extension by Microsoft. To do this, click on the Extensions icon in the sidebar (or press Ctrl+Shift+X), search for “Python,” and click on the “Python” extension by Microsoft.
  5. Click the “Install” button and wait for the installation to complete.

Congratulations! You have successfully installed Visual Studio Code and the Python extension. Your development environment is ready to go!

Configuring Python Interpreter

Before you can start writing and executing Python code within Visual Studio Code, you need to configure the Python interpreter. The Python interpreter is responsible for executing your code.

  1. Open Visual Studio Code.
  2. Select the View menu and click on Command Palette (or press Ctrl+Shift+P).
  3. In the command palette, type “Python: Select Interpreter” and select the option that appears.
  4. If you have multiple Python versions installed, choose the desired interpreter (e.g., “Python 3.9.6”).
  5. If you have a virtual environment set up for your project, select the interpreter associated with that virtual environment.
  6. Visual Studio Code will automatically set the selected interpreter for your current workspace.

Creating a Python Project

To create a new Python project in Visual Studio Code, follow these steps:

  1. Open Visual Studio Code.
  2. Select the View menu and click on Command Palette (or press Ctrl+Shift+P).
  3. In the command palette, type “Python: Create a new Python file” and select the option that appears.
  4. Enter a name for your Python file, including the .py extension (e.g., hello.py).
  5. Visual Studio Code will create a new file with the specified name.

Congratulations! You have created your first Python file in Visual Studio Code.

Running Python Code

To run your Python code within Visual Studio Code, follow these steps:

  1. Open the Python file you created or any existing Python file in Visual Studio Code.
  2. Write or paste your Python code into the file.
  3. To execute the code, you have a few options:
    • Click on the Run menu at the top and select Run Without Debugging (or press Ctrl+F5).
    • Right-click anywhere within the editor and select Run Python File in Terminal.
    • Use the keyboard shortcut Ctrl+F5 to run the code directly.

Visual Studio Code will execute your Python code and display the output in the integrated terminal.

Conclusion

In this blog post, we have learned how to set up your Python development environment using Visual Studio Code. We discussed choosing an IDE, installing Visual Studio Code, configuring the Python interpreter, creating a Python project, and running Python code within the IDE.

A well-configured development environment is crucial for productive Python programming. With Visual Studio Code and the Python extension, you’re equipped with powerful tools to enhance your coding experience.
