sqlite3.OperationalError: unrecognized token: "\"

This error occurs when SQLite encounters an invalid or unrecognized character in the SQL statement being executed. Specifically, this error message indicates that there is a backslash character ("\") in the SQL statement that is not being properly escaped.

To fix this error, you should check your SQL statement and ensure that any backslash characters are properly escaped. This typically involves adding an additional backslash before the existing backslash, like this:

SELECT * FROM my_table WHERE my_column = '\\'

Alternatively, you can use Python's raw string syntax to avoid the need for manual escaping:

c.execute(r"SELECT * FROM my_table WHERE my_column = '\'")
