Because parsing and unparsing (aka printing) are so trivial for s-expressions

At the innards of lisp and python are garbage collected data structures.
Building one with the other gets you that for free
[Doing it in a lower level language like C is what invokes the humorous:
Greenspuns tenth law]
So yes in that one respect what you say is true.
But then theres also (apart from parsing) all kinds of semantic differences eg:
- exceptions
- modules
- OOP milarky
- C interfacing in Baskin Robbins number of flavours
- carefully crafted portable veneer on top of intrinsically non portable OSes

All these have to be handled one way or other

A crucial difference between python and lisp is that python is
practical and lisp is utopian
