There's two similar concepts here.

1) Skeleton codegens. You do up some kind of template, run it through
a program, and get a ready-to-fill-in code structure. In this case,
you don't care so much about the translator's quality (if there's
bugs/limitations, you fix 'em after codegenning), and will maintain
the compiled code.

2) Compilation to Python. You write your program in some other
language, run it through a program, and get executable code out of it.
You want the translator to be perfect (so that you don't have to edit
the resulting code), and will maintain the original source.

I think the OP is looking for #2. I've used that sort of technique a
number of times (not with Python specifically, but with other
languages that lack certain handy features); usually the source is
trivially translateable into the output, with 99% of syntax identical
(for instance, one oft-wanted feature is a C-like #include - I've
written .php.m4 files that  get processed through M4 to become PHP
files).
