[New-bugs-announce] [issue31156] Stopiteration terminates while-loop
report at bugs.python.org
Wed Aug 9 05:49:19 EDT 2017
New submission from Günter Rote:
It should be mentioned in the documentation that
A StopIteration exception raised in the body of a while loop will terminate (and is caught by) the while-loop, thus leading to graceful termination.
A good place would be here:
I don't know how such a StopIteration termination of a while loop
affects the else-clause. This should be clarified.
it would be good to explicitly state:
An enclosing while-loop or for-loop acts like an implicit catch for StopIteration. The StopIteration exception will terminate the loop.
(I guess, a for-loop is also just terminated when the StopIteration originates in the BODY of the loop, although this is not the typical case.)
