New submission from Paddy McCarthy: http://docs.python.org/3.3/library/stdtypes.html?highlight=to_bytes#int.to_bytes and http://docs.python.org/3.3/library/stdtypes.html?highlight=to_bytes#int.to_bytes would benefit from an example showing what they do based on simpler coding.
I have such an example that I wrote here: http://paddy3118.blogspot.co.uk/2012/11/some-identities-for-python-inttobytes.html that you can use. I.e. >>> n = 2491969579123783355964723219455906992268673266682165637887 >>> length = 25 >>> n2bytesbig = n.to_bytes(length, 'big') >>> n2byteslittle = n.to_bytes(length, 'little') >>> assert n2bytesbig == bytes( (n >> i*8) & 0xff for i in >>> reversed(range(length))) >>> assert n2byteslittle == bytes( (n >> i*8) & 0xff for i in range(length)) >>> assert n == sum( n2bytesbig[::-1][i] << i*8 for i in range(length) ) >>> assert n == sum( n2byteslittle[i] << i*8 for i in range(length) ) >>> assert n == int.from_bytes(n2bytesbig, byteorder='big') >>> assert n == int.from_bytes(n2byteslittle, byteorder='little') >>> ---------- assignee: docs@python components: Documentation messages: 176671 nosy: docs@python, paddy3118 priority: normal severity: normal status: open title: Add examples to int.to_bytres and int.from_bytes type: enhancement versions: Python 3.3 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16580> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
