I believe "0o" offers some symmetry with the "0x" prefix used for hex literals. (And "0b" for binary.) It's a bit unfortunate that zero and capital "oh" are visually so similar. Not much to be done about that at this point. Just avoid upper case for all three prefixes. Skip -- https://mail.python.org/mailman/listinfo/python-list
