Hi,

I believe the parser module
<https://docs.python.org/3/library/parser.html> allows
for generation of a CST, though the documentation is not specific about the
type of syntax tree used. The old compiler module
<https://docs.python.org/2/library/compiler.html> utilized it for this
purpose and contains explicit documentation about getting a CST from the
parser module.
