Subject: [PATCH] add regex for python3 missing arguments err

add new regex and check for missing arguments.
The error message in python3 differs from the one in python2.

python3:
do_api() missing 1 required positional argument: 'url'

python2:
do_api() takes exactly 4 arguments (3 given)

To be compatible with python2 two checks are needed.
