How to Open and View Python (.py) Files on Windows 10

This article guides you through various methods to open, view, and execute Python (.py) files on your Windows 10 operating system, from basic text editors to integrated development environments.

Python is a versatile programming language, and its scripts are typically saved with the .py extension. If you're new to Python development on Windows 10, understanding how to open and interact with these files is a fundamental step. This guide will walk you through several common methods, catering to different levels of user experience and specific needs.

Method 1: Using a Simple Text Editor

The most straightforward way to view the contents of a Python file is using a basic text editor. This method is ideal for simply reading the code without executing it. Windows 10 comes with Notepad, but more advanced text editors like Notepad++ or Visual Studio Code offer better syntax highlighting and features.

1. Step 1

Right-click on the .py file you want to open.

2. Step 2

Select 'Open with' from the context menu.

3. Step 3

Choose 'Notepad' (or your preferred text editor like 'Notepad++' or 'VS Code') from the list.

4. Step 4

If your editor isn't listed, click 'Choose another app' and navigate to its executable.

Method 2: Executing Python Files via Command Prompt

To run a Python script, you need to have Python installed on your system. Once installed, you can execute .py files directly from the Windows Command Prompt or PowerShell. This method is essential for testing scripts and running console-based applications.

Workflow for executing a Python script via Command Prompt

1. Step 1

Ensure Python is installed on your Windows 10 system. You can download it from the official Python website.

2. Step 2

Open the Command Prompt or PowerShell. You can do this by typing cmd or powershell in the Windows search bar.

3. Step 3

Navigate to the directory where your .py file is located using the cd command. For example, if your file is in C:\Users\YourUser\Documents\PythonScripts, type cd C:\Users\YourUser\Documents\PythonScripts.

4. Step 4

Execute the Python script by typing python your_script_name.py and pressing Enter. Replace your_script_name.py with the actual name of your file.

cd C:\Users\YourUser\Documents\PythonScripts
python hello_world.py

Method 3: Using an Integrated Development Environment (IDE)

For serious Python development, an IDE offers a rich set of features including advanced code editing, debugging tools, project management, and direct execution capabilities. Popular Python IDEs include PyCharm, Visual Studio Code (with Python extension), and IDLE (which comes with Python).

1. Step 1

Install a Python IDE such as PyCharm Community Edition or Visual Studio Code.

2. Step 2

Open the IDE and use its 'Open File' or 'Open Folder' feature to load your .py file or the folder containing your project.

3. Step 3

Most IDEs provide a 'Run' button (often a green triangle icon) or a menu option to execute the current script directly within the IDE's integrated terminal.

Choosing the right method depends on your task. For a quick peek, a text editor is sufficient. For execution and basic testing, the command prompt is effective. For full-fledged development, an IDE is indispensable. By following these methods, you'll be able to confidently open, view, and run your Python files on Windows 10.
