Indeed. Most applications of do...while structures I can think of
seeing and using are actually of this form, and often emulate it with
something like (C):
... pre code ...
... post code ...
} while (test);
Other than just general lack of utility (you already have the structure
easily enough with while True and a break), I think the main aesthetic
reason it would be hard to add a
do...while/repeat...until/whatever...whatever structure is the
awkwardness of having two blocks as a fundamental part of some
looks obnoxious through my Pythonic secret decoder glasses.
