Answer 1

试一试：

        ## error
        (r'"[^"\\]*(\\.[^"\\]*)*.', 0, STYLES['error']),
        (r"'[^'\\]*(\\.[^'\\]*)*.", 0, STYLES['error']),

        # Double-quoted string, possibly containing escape sequences
        (r'"[^"\\]*(\\.[^"\\]*)*"', 0, STYLES['string']),
        # Single-quoted string, possibly containing escape sequences
        (r"'[^'\\]*(\\.[^'\\]*)*'", 0, STYLES['string']),
