我可以使用python装饰器基于输入类型来预处理输入和后处理输出吗？

def preprocess_input_and_postprocess_output(func):
    def wrapper(*args, **kwargs):
        # 预处理输入
        processed_args = []
        for arg in args:
            if isinstance(arg, str):
                processed_args.append(arg.strip())
            elif isinstance(arg, int):
                processed_args.append(arg * 2)
            else:
                processed_args.append(arg)
        
        # 调用原始函数
        result = func(*processed_args, **kwargs)
        
        # 后处理输出
        if isinstance(result, str):
            return result.upper()
        elif isinstance(result, int):
            return result // 2
        else:
            return result
    
    return wrapper

@preprocess_input_and_postprocess_output
def example_function(a, b):
    return f"Result: {a + b}"

# 测试装饰器
print(example_function("  hello ", 5))  # 输出: RESULT: 12
