py: Allow bytes/bytearray/array to be init'd by buffer protocol objects. Behaviour of array initialisation is subtly different for bytes, bytearray and array.array when argument has buffer protocol. This patch gets us CPython conformant (except we allow initialisation of array.array by buffer with length not a multiple of typecode). 2014-12-04 10:46:14 -05:00			`# test construction of bytes from different objects`

			`from array import array`

			`# tuple, list, bytearray`
			`print(bytes((1, 2)))`
			`print(bytes([1, 2]))`
			`print(bytes(bytearray(4)))`

			`# arrays`
			`print(bytes(array('b', [1, 2])))`
tests: Split byteorder-dependent tests to *_endian.py's. 2015-08-29 17:30:28 -04:00			`print(bytes(array('h', [0x101, 0x202])))`
objstr: Fix bytes creation from array of long ints. 2015-02-08 23:11:49 -05:00
			`# long ints`
			`print(ord(bytes([14953042807679334000 & 0xff])))`
tests: Add more tests to improve coverage, mostly testing exceptions. 2015-08-21 06:56:14 -04:00
