See PEP 315. Guido's rejection note is here:

seems fair enough; I suppose the cost is negligible or perhaps there's
peephole optimization for this common case.
Read the thread. Not having a dedicated feature means I counted at least
half a dozen different ideas for implementing what the OP really wanted
to do, which was expressed using C-like syntax. None of which were as
obvious.
And that C-like one worked because it could use an assignment within a
while-condition.
