Python Byte String Print Incorrectly In Dictionary

Consider a list contains data in byte (i.e ['\x03', '\x00', '\x32', ... ]) temp = b'' for c in field_data: temp += c print '%x' % ord(c) above code correctly concatenates a

Solution 1:

When you print a dict, it prints the braces { and } along with a representation of the contents.

>>>b = b'\x00\x0f\xff'>>>print b
�
>>>printrepr(b)
'\x00\x0f\xff'
>>>print {'test':b}
{'test': '\x00\x0f\xff'}

EDIT

The numbers 0x33 & 0x32 are the ASCII values of the characters '3' and '2'. repr will show printable ascii characters directly, while using the \x00 notation for non-printable characters.

>>>b = b'\x33\x32'>>>print b
32
>>>printrepr(b)
'32'
>>>hex(ord('3'))
'0x33'

Here's a function that I use for printing hex representations of strings

>>>defhexstr(s):...return'-'.join('%02x' % ord(c) for c in s)...>>>hexstr(b'\x00\xff\x33\x32')
'00-ff-33-32'

You might be able to subclass dict and override the __str__ representation if you want this to happen automatically.
