Is this meant to produce a tuple that contains inner tuples, or is it the same as tuple(i for i in range(10)) ? > This shouldn't result in ambiguity, since generators need to be in > parentheses anyway: > (i, for i in range(10)) vs (1, (i for i in range(10))) > Technically no, but it would be very confusing. (i for i in range(10)) # genexp (i, for i in range(10)) # your proposal ((i,) for i in range(10)) # genexp (i,1 for i in range(10)) # still error Is the comma just magic that says "tuple comprehension, not genexp"?
