New submission from Guilherme Polo <ggp...@gmail.com>:
Hi,
I find it weird that given this sample code:
def g():
yield iter(None)
list(*g())
I get this traceback:
Traceback (most recent call last):
File "a1.py", line 3, in <module>
list(*g())
TypeError: type object argument after * must be a sequence, not generator
At a minimum the exception message looks awkward to me. With the
proposed patch, the new traceback would be:
Traceback (most recent call last):
File "a1.py", line 3, in <module>
list(*g())
File "a1.py", line 2, in g
yield iter(None)
TypeError: 'NoneType' object is not iterable
