First, according to modern standard, 1 kilobyte contains 1000 bytes. 1024 bytes is 1 kibibyte. But in some applications 1 kilobyte means 1024 bytes. I do not even want to mention applications in which 1 "megabyte" is equal to 1000*1024 bytes. It all leads to confusion. Second, why use bytes units? Not every integer value measures the amount of memory. If you multiply 2 bytes by 3 bytes, do you get 6 square bytes? If you divide 60 by 5 bytes, do you get 12 reversed bytes? _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/5XHXJWFVEH4M2PIEKRHLKODO4FTIEUTQ/ Code of Conduct: http://python.org/psf/codeofconduct/
