Solved...
Ultimately an out-of-date simple_salesforce,
but complicated by the fact that my pip v9.0.1 attempt to upgrade
simple_salesforce (and even pip itself) also failed with a TLSV1 failure.
Stumbled upon this link - which had an answer that worked for me to get out
of this apparent infinite loop :-(
