Solve the following python programming problem given the following code:
def as_const(self, eval_ctx = None) : 
    eval_ctx = get_eval_context (const, eval_ctx) 
    def const(obj) : 
        if (obj is None) : 
            return None 
return obj.as_const (eval_ctx) 
return slice (const (self.start), const (self.stop), const (self.step)) 

    
    

    Fix the buggy line: eval_ctx = get_eval_context (const, eval_ctx)

#Here is Python program to fix the buggy line: eval_ctx = get_eval_context (const, eval_ctx)
.

eval_ctx = get_eval_context (self, eval_ctx)
