 This directory implements Python bindings for Clang.
 
+The bindings library requires at least Python version 3.7.

 You may need to set CLANG_LIBRARY_PATH so that the Clang library can be
 found. The unit tests are designed to be run with any standard test
 runner. For example:

Subject: [PATCH 3/3] [GitHub] Add python 3.7 to libclang python test

This enables the libclang python binding test to check
the oldest version of Python supported in addition
to the normal python version.

It is important to check this for issue #76664, since
many new mainstream python type annotation features
and best practices are not compatible with older
versions of python.

Additionally, frustration around ever increasing
platform dependencies and versions has been raised.
This will help ensure that python maintains reasonable
backwards compatibility.

Adding this additional build step will increase the
run time, but this should always be minimal, since
the additional libclang compilation should see 100%
cache hit rate.

Issue #76664.
Fixes #76601.
