macOS Catalina Unable to run .py script: Invalid Server Response

I get the following error:
python onenote_export.py --outdir ~/Downloads/onenote_export --select 'Personal'
File "onenote_export.py", line 62
raise RuntimeError(f'Invalid server response: {resp}')
^
SyntaxError: invalid syntax

Make sure you're using at least Python 3.6. you might have to replace python with python3 in the command.
