Terry J. Reedy <tjre...@udel.edu> added the comment:
Devs are aware that there is an exception to the general rule for the 'for'
clause. There is a technical reason why the exception is possible, though I
have forgotten it.
Since you already know that changing the general behavior has been rejected,
are you asking that the exception be removed (for consistency) , so that your
first example would fail? If so, that will be rejected also.
I am changing this to a doc issue in case you or someone else wishes to suggest
a doc improvement.
The solution to the limitation on generator expressions, of course, is to write
out the generator one is trying to abbreviate.
def clipper(max):
for i in range(5):
if i < max:
yield i
class Foo:
x = 3
y = list(clipper(x))
print(Foo.y)
# [0, 1, 2]
