Force usage of Python 3

[theel0ja]

On Debian10, python automatically points to Python 2.

Fixes #14 as well.

Thanks for the pr!
However, I'm not sure how to handle this the best way. I'd think it would be the best practice to let the distribution itself define the default version of Python to use, this is also in order to keep the script distribution agnostic. It is compatible with both Python 2 and 3 anyway.

What do you think?

Newer Debian versions only have Python 3 installed out-of-the-box:

daniel@ny02:~$ python --version
-bash: python: command not found
daniel@ny02:~$ python3 --version
Python 3.8.3

So the shebang currently in this script doesn't work properly.

Since Python 2 is EOL and everyone should be migrating to Python 3, IMO it makes sense to change the shebang to hard-code python3.

Just found this because even though latest Ubuntu has python2.7 they took out the python-requests 2.7 package...couldn't figure out if/how to make this run with python3 so I had to do a hacky fix to the imports :/

This can be solved by installing the python-is-python3 package.

• Python 2.7 is End of Life
• Most distros use python3 for Python 3.x
• The code is now supported for Python 3, just naming it explicitly
