If you don't have to treat it as an atom, you can simplify that to
just
(?!_|\d)\w+
which just means that the first character can't be an underscore or
digit.
Though for a Py3 identifier, the underscore is acceptable as a first
character ("__init__"), so you can simplify it even further to just
(?!\d)\w+
