Solve the following python programming problem given the following code:
def attrs(self) : 
    if ('(' == self.input [0]) : 
        index = self.indexOfDelimiters ('(', ')') 
        string = self.input [1 : tok]

            literal = True 
            def reset(self) :

        def state() : 
            return states [(- 1)]

            (attr, num) = self.RE_ATTR_INTERPOLATE.subn ((lambda matchobj : ('%s+%s+%s' % (ns.quote, matchobj.group (1), ns.quote))), attr) 
            return (attr, (num > 0)) 
self.consume ((index + 1)) 
        from utils import odict 
        tok.attrs = odict () 
        tok.static_attrs = set () 
        str_nums = map (str, range (10)) 
        def parse(c) : 
            real = c 
            if (colons and (':' == c)) : 
                c = '=' 
ns.literal = (ns.literal and (state () not in ('object', 'array', 'expr')))

                    states.append ('key') 
                    ns.val = ns.val.strip () 
                    ns.key = ns.key.strip () 
                    if (not ns.key) : 
                        return 
if (not ns.literal) : 
                        if ('!' == ns.key [(- 1)]) : 
                            ns.literal = True

                        (tok.attrs [ns.key], is_interpolated) =...

    
    

    Fix the buggy line: string = self.input [1 : tok]

#Here is Python code to fix the buggy line: string = self.

string = self.input [1 : index]
