How to : Python Convert Bytes to Readable ASCII/Unicode
提问by
this is the bytes i have received,and i would like to convert byte[5] + byte[6] + byte[7] + byte[8] to ASCII readable text.
这是我收到的字节，我想将字节 [5] + 字节 [6] + 字节 [7] + 字节 [8] 转换为 ASCII 可读文本。
s=b'0f0000004e52303947303531363400'
bytes[5]~[8] ASCII/UNICODE is NR09
字节[5]~[8] ASCII/UNICODE 是 NR09
please help thanks.
请帮忙谢谢。

bytes.fromhex(s[4*2:8*2].decode("ascii")).decode("ascii")
//'NR09'
Btw, this would be much easier if you didn't use the conversion from Python : convert a hex string
顺便说一句，如果您不使用Python的转换，这会容易得多：convert a hex string
In that question you have:
在那个问题中，你有：
b'\x0f\x00\x00\x00NR09G05164\x00'
So you can do
所以你可以做
c = b'\x0f\x00\x00\x00NR09G05164\x00'
c[4:8].decode("ascii")
//'NR09'

>>> s.decode("hex")[4:8]
'NR09'
