`
STYLES = {
    'string'   : format('magenta') ,
    'error'    : format('red' , 'underline') ,
}
rules +=[(r'"[^"\\]*(\\.[^"\\]*)*', 0, STYLES['error']),
         (r'"[^"\\]*(\\.[^"\\]*)*"', 0, STYLES['string']),]
`

Answer 1

试试看：

        ## 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']),
