Q:

Python on Server: What does the following error message mean?

I have a python that works perfectly fine when I let it run via a 
local python server on my machine. So, I uploaded it on a server,
set the correct permission octals and then tried to access the
.cgi file via the browser.It doesn't run, but I get the following message:
The following python binaries are available:

python3: Python 3.7.7

Please use the binary for the version of Python you want.

As I am new to Python, I don't know how to interprete this.
Thank you.

A:

Your cgi file probably has a line at the top that looks something like this:
#! /usr/bin/python

Change python to python3.
