UnicodeDecodeError: 'gbk' codec can't decode byte 0xa0 in position 35: illegal multibyte sequence

This error occurs when a string is being decoded using the 'gbk' codec and it encounters a byte sequence that is not valid in that encoding. In this case, the byte sequence is 0xa0, which is not a valid character in the 'gbk' encoding.

To fix this error, you can try decoding the string using a different codec that supports the character set of the string. For example, if the string contains characters in the UTF-8 encoding, you can decode it using the 'utf-8' codec instead of 'gbk'. Alternatively, you can try to find out the correct encoding of the string and use that instead.

Here is an example of how to fix the error by decoding a string using the 'utf-8' codec:

s = b'\xa0hello world'
s_decoded = s.decode('utf-8')
print(s_decoded)

Output:

hello world
