Solve the following python programming problem given the following code:
def _print_repr(self, typename) : 
    print ("
    def __repr__(self):
        return ('{typename}(' ".rstrip ().format (typename = typename)) 
    first = True 
    for (type, name, nullable, plural) in self._fields : 
        print ("                '{comma}{name}={{self.{name}!r}}'".format (comma = (', ' if (not first) else ''), name = snake (first))) 
        first = False 
print ("                ')').format(self=self)") 

    
    

    Fix the buggy line: print ("                '{comma}{name}={{self.{name}!r}}'".format (comma = (', ' if (not first) else ''), name = snake (first)))
