如何将我的bytearray('b\x9e\x18K\x9a')转换为类似这样的东西 - >'\ x9e\x18K\x9a'<---只是str,而不是数组

Question

如何将我转换bytearray('b\x9e\x18K\x9a')为这样的东西 - > \x9e\x18K\x9a<---只是str,而不是数组!

>> uidar = bytearray()
>> uidar.append(tag.nti.nai.uid[0])
>> uidar.append(tag.nti.nai.uid[1])
>> uidar.append(tag.nti.nai.uid[2])
>> uidar.append(tag.nti.nai.uid[3])
>> uidar
   bytearray('b\x9e\x18K\x9a')

我尝试解码我​​的bytearray

uid  =  uidar.decode('utf-8')

但它不能......

Traceback (most recent call last):
  File "<pyshell#42>", line 1, in <module>
    uid = uidar.decode("utf-8")
  File "/usr/lib/python2.7/encodings/utf_8.py", line 16, in decode
    return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0x9e in position 0: invalid start byte

请帮帮我 ...

在2.x中,字符串是字节串.

>>> str(bytearray('b\x9e\x18K\x9a'))
'b\x9e\x18K\x9a'

Latin-1将前256个字符映射到它们的bytevalue等价物,因此在Python 3.x中:

3>> bytearray(b'b\x9e\x18K\x9a').decode('latin-1')
'b\x9e\x18K\x9a'
