>>> (50,) * 2
(50, 50)
>>> 50, * 2
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
TypeError: 'int' object is not iterable

This message is confusing. It isn't clear that 50.__iter__ is called. tuple(50)*2 seems to happen, which isn't expected (at least to regular users). Not like "50 * 2," that relates to parsing.

>>> '1', * 2
Traceback (most recent call last):
  File "<stdin>", line 3, in <module>
TypeError: 'int' object is not iterable

Update: 2.__iter__ seems to be called.

Just updated to 3.9. Fixed.
