Serhiy Storchaka added the comment:
Here is a patch based on current str formatting code (i.e. parenthesis are
added only if needed, the space at the right is used more efficiently). It adds
pprint support for bytes and bytearrays. Bytes are broken only at positions
divisible by 4, so packed 32-bit ints are never broken.
Examples:
>>> pprint.pprint(bytes(range(128)))
(b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f\x10\x11\x12\x13'
b'\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f !"#$%&\'()*+,-./01234567'
b'89:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{'
b'|}~\x7f')
>>> pprint.pprint({'abcdefgh': bytes(range(128))})
{'abcdefgh': b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'
b'\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f'
b' !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ['
b'\\]^_`abcdefghijklmnopqrstuvwxyz{|}~\x7f'}
>>> pprint.pprint(bytearray(range(128)))
bytearray(b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'
b'\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1a\x1b\x1c\x1d\x1e\x1f'
b' !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_'
b'`abcdefghijklmnopqrstuvwxyz{|}~\x7f')
>>> pprint.pprint({'abcdefgh': bytearray(range(128))})
{'abcdefgh': bytearray(b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b'
