Ok, so you want to implement a domain specific language (DSL) for function
First thing to ask: how expressive do you want this language to be? If the
answer is "as expressive as the code it describes", then you will end up
needing a turing-complete programming language, in which case you may want
to use plain Python code instead of writing your own language. See the
Implementing a language that can express "x*3" is relatively(!) easy, but I
would guess that you want your post conditions to be a little more
expressive than that.
Could you describe why you want such a language in the first place? What
feature do you need that cannot be expressed using doctests, for example?
