"Python does have access to the abstract syntax tree of programs, but this is not for the faint of heart. On the plus side, the modules are easy to understand, and with five minutes and five lines of code I was able to get this: >>> parse("2 + 2") ['eval_input', ['testlist', ['test', ['and_test', ['not_test', ['comparison', ['expr', ['xor_expr', ['and_expr', ['shift_expr', ['arith_expr', ['term', ['factor', ['power', ['atom', [2, '2']]]]], [14, '+'], ['term', ['factor', ['power', ['atom', [2, '2']]]]]]]]]]]]]]], [4, ''], [0, '']] "This was rather a disapointment to me. The Lisp parse of the equivalent expression is (+ 2 2). It seems that only a real expert would want to manipulate Python parse trees, whereas Lisp parse trees are simple for anyone to use." -- Peter Norvig, https://norvig.com/python-lisp.html https://norvig.com/python-lisp.html
