How to convert bytearray with non-ASCII bytes to string in python?
提问by Karel Bílek
I don't know how to convert Python's bitarray to string if it contains non-ASCII bytes. Example:
如果 Python 的位数组包含非 ASCII 字节，我不知道如何将其转换为字符串。例子：
>>> string='\x9f'
>>> array=bytearray(string)
>>> array
bytearray(b'\x9f')
>>> array.decode()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0x9f in position 0: ordinal not in range(128)
In my example, I just want to somehow get a string '\x9f' back from the bytearray. Is that possible?
在我的示例中，我只想以某种方式从字节数组中获取字符串 '\x9f' 。那可能吗？

In Python 2, just pass it to str():
在 Python 2 中，只需将其传递给str()：
>>> import sys; sys.version_info
sys.version_info(major=2, minor=7, micro=8, releaselevel='final', serial=0)
>>> string='\x9f'
>>> array=bytearray(string)
>>> array
bytearray(b'\x9f')
>>> str(array)
'\x9f'
In Python 3, you'd want to convert it back to a bytesobject:
在 Python 3 中，您希望将其转换回bytes对象：
>>> bytes(array)
b'\x9f'

I'd like to mention the binasciilibrary that comes with Python.
我想提一下binasciiPython 自带的库。
My use case: I was querying a database that had a binary field being used as a key within the DB. I wanted to pull that binary field and treat it as a key elsewhere. I thought converting it to a string was the best use-case.
我的用例：我正在查询一个数据库，该数据库有一个二进制字段用作数据库中的键。我想拉那个二进制字段并将其视为其他地方的密钥。我认为将其转换为字符串是最好的用例。
binascii offered me a better alternative:
binascii 为我提供了一个更好的选择：
import binascii
binary_field = bytearray(b'\x92...')
binascii.hexlify(binary_field)
import binascii
binary_field = bytearray(b'\x92...')
binascii.hexlify(binary_field)
