Solve the following python programming problem given the following code:
def __str__(self) : 
    out = '' 
    def replace_header(match) : 
        return ('"' * (match.end () - match.start ())) 
for m in self.methods : 
        print (('Parsing `%s`' % m)) 
        out += (str (FunctionDoc (getattr (self._cls, m))) + '

') 
        out += ('.. index::
   single: %s.
%s

' % (m._name, m)) 
return out 

    
    

    Fix the buggy line: out += ('.. index::
   single: %s.
%s

' % (m._name, m))
assistant
#Here is Python code to fix the buggy line: out += ('.

out += ('.. index::
   single: %s; %s

' % (self._name, m))
