Traceback most recent call last File CUsersNewAppDataRoamingJetBrainsPyCharm20231scratchesscratch_1py line 5 in module folders = freadsplitlinesUnicodeDecodeError gbk codec cant decode byte 0x80 i

This error occurs when the Python interpreter is not able to decode a byte sequence using the 'gbk' codec. The 'gbk' codec is used to encode and decode text in the Chinese language. The error message indicates that there is an illegal multibyte sequence in position 18 of the byte sequence.

To fix this error, you can try the following steps:

1. Open the file in a text editor that can handle different encodings, such as Notepad++.

2. Save the file with the 'UTF-8' encoding.

3. Change the Python code to specify the 'UTF-8' encoding when opening the file. For example:

   with open('folders.txt', 'r', encoding='utf-8') as f:
       folders = f.read().splitlines()
   

   This will tell Python to use the 'UTF-8' codec to decode the byte sequence from the file.

By following these steps, you should be able to read the file without encountering the UnicodeDecodeError
