Using the Python Selector in cPanel

The Python Selector in cPanel allows you to create and manage Python applications directly from your hosting account. It provides an easy way to select Python versions, configure virtual environments, and run applications without needing manual server setup.

Why Use Python Selector?

• Run Python applications on shared hosting.
• Choose from multiple Python versions.
• Manage dependencies with pip inside a virtual environment.
• Simplify deployment without complex server configuration.

Creating a Python Application

1. Access Python Selector

1. Log in to cPanel.
2. On the Tools page → Software section, click Setup Python App.

2. Create a New Application

1. Click Create Application.

2. Fill in the following fields:

   • Python Version → Select the version you want (e.g., 3.9, 3.11).
   • Application Root → Enter the directory where your app files are stored (e.g., /home/username/myapp).
   • Application URL → Define the domain or subdomain that will serve the app.
   • Application Startup File → Specify the entry point file (e.g., app.py).

3. Click Create.

3. Manage Dependencies

• After creating the app, you can install packages using pip inside the virtual environment.

• Example:

  pip install flask

• Use the Run Pip Install button in the Python Selector interface to install dependencies from your requirements.txt file.

4. Restart and Test

• Restart the application from the Python Selector dashboard after making changes.
• Visit the Application URL to confirm it runs correctly.
• Use Error Logs in cPanel to troubleshoot issues.

Note

• Always restart the app after modifying files or dependencies.
• Ensure your requirements.txt file is properly configured for easier dependency management.
• Python Selector creates a virtual environment for each application, isolating dependencies.
