Since Python already has a while <condition>: loop, I'm supposing you
mean something like
do:
<some code>
while <not condition>
or
do:
<some code>
until <condition>
Is that what you mean? In some languages that might be a "do x until y"
loop, which I would suppose has been proposed before for Python. A
clean syntax might be
until <condition>:
<some code>
... except that people seem to object to placing the condition
specification so far from where the test would actually take place (at
the bottom of the loop). I don't have a problem with that, but I can see
why many would. It doesn't seem Pythonic somehow.
There was a long thread about a loop-and-a-half construction where some
of this was discussed, though I don't have a link for that.
In any case, what would you want to do that you can't do (in some way)
now? If you have a compelling use case, you could get a bit more
attention than merely offering a suggested expansion of the language.
