Testing Python Functionality with a “Hello World” App (Firstserv Guide)

If you're having issues with a custom Python application, a good first step is to confirm that the Python service itself is working correctly. You can do this by creating a simple “Hello World” application.

Important Notes

• Firstserv supports the Python service and environment only
• Troubleshooting your custom application, dependencies, or code is outside our support scope
• For more advanced or production-level Python applications, we recommend using a VPS or dedicated environment

Step 1: Create a Python Application

1. Log in to your cPanel account
2. Navigate to the Software section
3. Click Setup Python App

Create the Test App

1. Click Create Application (top right)

2. Configure the following:

   • Application Root: helloworld
   • Application URL: helloworld

3. Click Create

Step 2: Access Your Test Application

Once created, visit your test app in your browser:

https://yourdomain.com/helloworld

What This Test Confirms

• ✅ If the page loads successfully, the Python service is running correctly
• ❌ If not, there may be an issue with the underlying Python environment

Next Steps

If your test app works but your main application does not, the issue is likely within your application itself. You may need to check:

• Installed Python modules and dependencies
• Application configuration and environment variables
• Error logs within your application

Summary

Creating a simple Python test app helps confirm whether:

• ✅ The server and Python environment are functioning correctly
• ❌ The issue is specific to your application setup

If you need help confirming your Python environment is operational, the Firstserv support team is happy to assist.
