如何解码存储在python3变量中的非b前缀字符串，例如'\\ xd0 \\ xbc'？

Question

I have some variable from API. For example:

a == '\xd0\xbc'

I need to get variable b by decoding a:

b == 'М'

But I can't write in code something like this:

a = b'\xd0\xbc'
b = a.decode()

because this text (\\xd0\\xbc) is already in the variable.

Answer 1

will this help ? I would guess there is a better way however I do not know it

>>> a = r'\xd0\xbc'
>>> b = 'b"{}"'.format(a)
>>> c = eval(b)
>>> d = c.decode()
>>> d
'\u043c'

Answer 2

You need to use str.encode() and pass encoding="latin" to get b == 'M' .

a = str.encode('\xd0\xbc', 'latin')
b = a.decode()
print(b)

If "latin" is not the standard encodings you were looking for, try others .
