项目文件夹：

• 仅需三个.py文件：test.py、test/init.py、test2.py

test文件夹：

• __init__.py：包含以下代码

  from .test2 import *

• test2.py：定义多个函数

  __all__ = ['ResNet', 'resnet18', 'resnet34', 'resnet50', 'resnet101']def ResNet():    print('ResNet')def resnet18():    print('resnet18')def resnet34():    print('resnet34')def resnet50():    print('resnet50')def resnet101():    print('resnet101')

test.py文件：

import testclass Test:    def __init__(self, model_name='', age='', sex=''):        self.model_name = model_name        self.age = age        self.sex = sex        print('self.model_name', self.model_name)        print('self.age', self.age)        print('self.sex', self.sex)    def __call__(self):        print('调用函数')new_test = Test(test.__dict__['resnet50'], '18', 'boy')print('----------')test.__dict__['resnet50']()print(new_test.model_name)new_test.model_name()

• 输出显示调用了resnet50函数，并打印了模型名、年龄和性别。
• 结果显示new_test.model_name为'18'，并且调用了函数。
