Why is it throwing an error when opening a .html file in python?
tell me how to open the file. Tried double \\ did not help.

Answer 1

Try raw string r'C:\\ or r'''C:\Users\...'''.
\U in "C:\Users ..." triggers an eight-character Unicode escape.
And it's better to switch to Linux or MacOs.

Answer 2

Check the encoding, it might not be utf-8.
