Hi folks,
it is possible to close a generator. That is (among others) for the
following case:
I run a for loop over the iterator, but then I break it. Now I can leave
the generator to the GC (which is AFAI have been told a thing which I
should not do), or I can clean up myself.
That is very rarely necessary. generator.close was added so that one
could tell the generator to close anything opened within the generator,
such as a file, that needs to be explicitly closed.
Example:
for i in g:
if i is not None:
g.close()
return i
When returning from the function, g, if local, should disappear.
