1.To create a Python app in cPanel, you would start by logging into cPanel.
2. In the Software section click on "Setup Python App".
3. Click the "Create Application" button to configure the settings for your new app.
4. You can choose between versions of the Python language - either 2.7.18, 3.5.9, or 3.7.8 - by clicking on the blue dropdown arrow.
5. Choose the Application URL and Application root directory where your Python files will live. Note, you cannot use public_html for the Application root directory, so it should be a new folder or an existing sub-directory.
6. You can add Environment variables before creating your application by clicking "Add Variable" near the bottom of the screen.
Each variable must have a name and a value. In the example below, the name is x and the value is 5, so x=5 would be the variable created.
Click "Done" to save any added environment variables.
7. Click Create when you are ready to create your Python app. The creation process may take a minute or two.
8. When you are finished you will be given a terminal command at the top of the screen similar to:
source /home/reselle1/virtualenv/app/2.7/bin/activate && cd /home/reselle1/app
9. At this point you can cancel, stop, restart, or destroy your Python app from this screen.
10. To enter the Python virtual environment, enter the terminal command into a Terminal within cPanel. To get there, click: 
near the top left of the screen then click: 
11. Once you have entered the command similar to source /home/reselle1/virtualenv/app/2.7/bin/activate && cd /home/reselle1/app
you can just type the command: python to be entered into a Python shell/interpreter to enter Python code.
12. You can load your Python app in a web browser by going to http://yourapplicationurl.com/pythonfoldername
NOTE: Python app development is outside our scope of support. Like any development project, you would need to refer to Python documentation or your own developer for assistance debugging any applications. To learn more about Python you can go to: https://www.python.org/about/gettingstarted/
