如何解码字节对象的字符串表示形式？
问题描述：
我有一个字符串，其中包含编码的字节：
I have a string which includes encoded bytes inside it:
str1 = "b'Output file \xeb\xac\xb8\xed\x95\xad\xeb\xb6\x84\xec\x84\x9d.xlsx Created'"
我想对其进行解码，但是由于它已经变成字符串，所以我不能。因此，我想问是否有任何方法可以将其转换为
I want to decode it, but I can't since it has become a string. Therefore I want to ask whether there is any way I can convert it into
str2 = b'Output file \xeb\xac\xb8\xed\x95\xad\xeb\xb6\x84\xec\x84\x9d.xlsx Created'
这里 str2 是一个 bytes 对象，我可以对其进行解码
Here str2 is a bytes object which I can decode easily using
str2.decode('utf-8')
以获得最终结果：
'Output file 문항분석.xlsx Created'
答
一种简单的方法是假定初始字符串的所有字符都在[0,256）范围内，并映射到相同的Unicode值，这意味着它是Latin1编码的字符串。
A simple way is to assume that all the characters of the initial strings are in the [0,256) range and map to the same Unicode value, which means that it is a Latin1 encoded string.
然后琐碎：
str1[2:-1].encode('Latin1').decode('utf8')
