Solve the following python programming problem given the following code:
def _make_setter(self, segment, class_) : 
    obj = getattr (class_, self, None) 
    if (obj is not None) : 
        if hasattr (obj, '__set__') : 
            def setter(target, value, x = obj.__set__) : 
                x (target, value) 
return setter 
obj = class_.__dict__.get (segment) 
    if ((obj is not None) and hasattr (obj, '__set__')) : 
        def setter(target, value, x = obj.__set__) : 
            x (target, value) 
return setter 
if hasattr (class_, '__getitem__') : 
        def setter(target, value) : 
            target [segment] = value 
return setter 
if hasattr (class_, '__dict__') : 
        def setter(target, value) : 
            target.__dict__ [segment] = value 
return setter 
raise RuntimeError (('unable to resolve attribute setter for %r on %r' % (segment, class_))) 

    
    

    Fix the buggy line: obj = getattr (class_, self, None)

#Here is Python code to fix the buggy line: obj = getattr (class_, self, None)
.

obj = getattr (class_, segment, None)
