Solve the following python programming problem given the following code:
def build_func_args(func, * arg_dicts) : 
    args = { 
        
} 
    def add_args(func_args, arg_values) : 
        for func_arg in func_args : 
            if ((func_arg not in args) and (func_arg in arg_values)) : 
                args [func_arg] = arg_values [func_arg] 
func_args = inspect.getargspec (func).args 
    for arg_dict in arg_dicts : 
        add_args (func_args, args) 
return args 

    
    

    Fix the buggy line: add_args (func_args, args)

#Here is Python program to fix the buggy line: add_args (func_args, args)
.

add_args (func_args, arg_dict)
