[issue19697] Document the possible values for __main__.__spec__

Eric Snow added the comment: That did the trick, Nick. I swear there's always something I forget about ReST. :) Otherwise do you have any objections to the patch? I imagine there's more we could put in the section (for language spec purposes), but I figure what I have there is good enough

[issue21014] `1` = `True`; for tutorial docs

Raymond Hettinger added the comment: Samuel, thanks for the patch. And, Terry, thanks for looking at it. Applied the first two changes to 3.4 and 3.5. Skipped, the third suggested change in introduction.rst. That was not a boolean example, it was just the number 1 in a section about how

[issue20895] Add bytes.empty_buffer and deprecate bytes(17) for the same purpose

Josh Rosenberg added the comment: Why would we need bytes.fill(length, value)? Is b'\xVV' * length (or if value is a variable containing int, bytes((value,)) * length) unreasonable? Similarly, bytearray(b'\xVV) * length or bytearray((value,)) * length is both Pythonic and performant. Most

[issue21091] EmailMessage.is_attachment should be a method
