given the following code
def g():
yield 2
yield 3
return 6
for x in g():
print(x)
The output is obviously
2
3
As far as I know, there is currently no way to capture the
StopIteration value when the generator is used in a for loop. Is it
true?
If not, would a syntax like:
for x in g() return v:
print(x)
print(v) # prints 6
be useful? It would be syntactic sugar for (corner cases omitted)
def g():
yield 2
yield 3
return 6
it = iter(g())
while True:
try:
x = next(it)
except StopIteration as exc:
v = exc.value
break
else:
print(x)
print(v)

Kind regards,
