How to convert "byte" string to bytes?

Question

Python

The server using json returns the string sign and publickey (electronic signature, rsa module ).
There was a problem with the transfer of the signature, because. it is bytes , but I cannot decode it into a string, because invalid start byte . I have to pass it as a string, without decoding.
It turns out that in the program I get str: b'5\xbe`\x00=\xd6\xd8h\x1f[`'
Verification works only with bytes, but when I try to do bytes(), it gives out something like bytes: b"b'5\xbe`\x00=\xd6\xd8h\x1f[`'", i.e. two times b, and, of course, the check fails. How can this string
be converted to bytes, given that it already contains bytes? Or how can I transfer the signature (bytes) differently?
