-====== sandbox python ======
-===== Python Scripts =====
-I can test my python script from the command line. \\
-python index.cgi \\
-In the default a2hosting account, I can run any version of python. \\
-python --version \\
-python3 --version \\
-python3.7 --version \\
-I can also create a virtual environment, in which I can use pip to install packages. \\
-Then I can use this environment to run cgi scripts. \\
-===== Python Web App =====
-We already have python cgi available, as in index.cgi.
-But cgi is not an efficient way to run python.
-So now we will setup a more modern python implementation. \\
-See a2hosting docs here. \\
-[[http://www.a2hosting.com/kb/cpanel/cpanel-software/using-the-python-selector|How to use the Python Selector in cPanel]] \\
-[[http://www.a2hosting.com/kb/developer-corner/python|Python Articles]] \\
-==== Web Server Gateway Interface (WSGI) ====
-In cPanel, Setup Python App, Create Application.
-Fill in the form thusly:
-  * Python version:  3.7.12
-  * Application root:  /home/username/webprod/sandbox/sandbox/html/pvc
-  * Application URL: sandbox.voyc.com/pvc
-  * Application startup file: passenger_wsgi.py   (default, created automatically)
-  * Application Entry point: application    (default, the name of a function in the startup file)
-  * Passenger log file: /home/username/logs/user/sandbox.py.log
-Evidently this is Phusion Passenger. \\
-From the URL we can call only one python function: the Entry Point in the Startup File. \\
-Page navigation must be handled by the entry point function. \\
-Presumably one could create multiple applications on one subdomain? \\
-The Application Root is similar to DocRoot. \\
-The setup creates this folder and installs the startup file and three folders. \\
-passenger_wsgi.py  public/  __pycache__/  tmp/ \\
-This application can be stopped, restarted, and destroyed from the cPanel page. \\
-I sometimes need to do a restart to make my program changes take effect.  \\
-==== Virtual Environment ====
-The cPanel, Setup Python App, program already created a virtual environment for this app.
-Its location is /home/username/virtualenv/webprod/sandbox/sandbox/html/pvc/3.7.
-This folder contains bin/, lib/, and lib64 folders.
-To activate this enviroment offline.
-source /home/username/virtualenv/webprod/sandbox/sandbox/html/pvc/3.7
-Then I can install packages using Pip, and these packages are available to the web app as well.
-==== websockets ====
