'utf-8' codec can't decode byte 0xd0 in position 0: invalid continuation byte

This error message usually appears when Python is trying to read a file or string that contains characters that are not in the UTF-8 encoding. UTF-8 is a popular character encoding scheme used to represent text in computers.

The byte 0xd0 is a non-UTF-8 character that Python cannot decode. This byte may have been introduced by copying and pasting text from a non-UTF-8 source, or it may be a result of reading a file that is not encoded in UTF-8.

To fix this error, you can try the following:

1. Check the encoding of the file or string you are trying to read. If it is not UTF-8, you may need to specify the correct encoding when reading the file or converting the string.

2. Use a text editor that supports UTF-8 encoding and re-save the file in UTF-8 format.

3. If the non-UTF-8 character is a result of copying and pasting text, try typing the text directly into the program or use a tool to convert the text to UTF-8 before copying and pasting.

4. If you are still having issues, you may need to use a different encoding library or tool to handle the non-UTF-8 characters.
