Python

The easiest way to get started with Python on a server is with CGI. Really the only difference between CGI and running the script on your home computer is CGI needs to output a "Content-Type" header.
Steps
Open the File Manager in cPanel
Double click public_html
Double click cgi-bin
In the top left click + File
Type test.py as your filename
Click Create New File
Highlight the test.py file and click Permissions
Check execute on all three columns so it says 755
Click Change Permissions
Click reload and make sure the 755 shows up under the permissions column
Highlight test.py and click Editor
Leave UTF-8 as the encoding and click Edit
Copy/paste this in:
#!/usr/bin/python3.10
​
print("Content-Type: text/html\n\n")
​
print("Heliohost rules!")
Click Save Changes
Go to <your subdomain>.heliohost.org/cgi-bin/test.py
If everything worked it should say Heliohost rules! in your browser. The first line is the shebang. That's what tells the server which version of python to use. On Tommy and Johnny you can pick between:
Path
Version
#!/usr/bin/python2.7
2.7.13
#!/usr/bin/python3.7
3.7
and python3.6 for Ricky.
The next line is the Content-Type header. This is important so the server knows what to do with the output that follows. If you forget it your script will give a useless 500 error. The content type header always has to have the two end lines immediately after it. That's what the  is.
Modules
You can see the modules that are currently installed on the Python versions:
Johnny
​Python 2.7​
​Python 3.6​
​Python 3.10​
Ricky
​Python 2.7​
​Python 3.6​
Tommy
​Python 2.7​
​Python 3.6​
​Python 3.10​
If you don't see the module you need your script will probably give a useless 500 error when you try to import the missing module. Just make a post on the forums stating your server, the version of python you're using, and the module(s) you need.
Extra: Python scripts outside cgi-bin folders
Executing a CGI script outside the cgi-bin folder is possible with some modifications.
Steps
Go to /home/<your username>/public_html.
Create a file named .htaccess and copy/paste this in:
Options +ExecCGI
AddHandler cgi-script .py
DirectoryIndex index.py
The first two lines make .py files executable outside cgi-bin, and the last line makes the filename index.py show up if someone goes to your domain without having to type out the filename like domain.heliohost.org/index.py. This also supports other CGI file extensions.

Path	Version
#!/usr/bin/python2.7	2.7.13
#!/usr/bin/python3.7	3.7
