How to Execute Python Scripts in Windows

Python is a versatile and widely-used programming language, and executing Python scripts on a Windows operating system can be straightforward. This guide will guide you through the necessary steps to run your Python scripts effectively on a Windows machine.

Install Python

Before executing Python scripts, ensure Python is installed on your system:

Visit the Official Python Website: Go to the Python official website and download the latest version of Python.

Run the Installer: Execute the downloaded installer and follow the setup instructions.

Add Python to PATH: During installation, make sure to check the option that says "Add Python to PATH." This ensures that Python commands will be recognized in the command prompt.

Verify Python Installation

After installation, it is prudent to verify if Python is correctly installed and added to PATH:

Open Command Prompt: Press Win + R, type cmd, and press Enter.

Check Python Version: In the command prompt, type python --version or python -V. If Python is installed and correctly added to PATH, you should see the installed version number.

Writing Your Python Script

Create your Python script using a text editor of your choice (Notepad, Sublime Text, VS Code, etc.):

Open Text Editor: Open any text editor.

Write Python Code: Write your Python script. For example:

If everything is set up correctly, you should see the output of your script in the command prompt.

Configuring Environment Variables (Optional)

If you face any issues with executing Python from the command prompt, configuring environment variables can help:

Open System Properties: Press Win + Pause/Break, select 'Advanced system settings', and then click on 'Environment Variables'.

Edit the PATH Variable: Under 'System variables', scroll to find the 'Path' variable, select it, and click 'Edit'.

Add Python Path: Ensure that the directories where Python is installed (e.g., C:\Python39\, C:\Python39\Scripts\) are added to the PATH environment variable.

Final Thoughts

Running Python scripts on Windows is a simple and essential skill for any developer working with Python. By following these steps, you can easily execute your Python code and automate tasks within your Windows environment. Happy coding!
