步骤1:编写Python脚本 首先,我们需要创建一个Python脚本,示例代码如下: # 导入sys模块importsys# 定义main函数defmain():# 这里可以添加你的代码逻辑pass# 判断是否为主程序入口if__name__=="__main__":main() 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 步骤2:在main函数中指定a
print(a,b,args)# args接受 多个参数存储类型为元组 func(1,2,3,4,5) 结果为: 1 2 (3,4,5)def func(a,b,args):#args是万能(接受任意多个)的位置参数 *在函数定义的时候叫做聚合 print(a,b,args) func(1,2,3) 结果为: 1 2 (3,)def func(a,b,args):#args是万能(接受任意多个)的位置参...

Process(target=function1, args=(2,)), ] [p.start() for p in process] # 开启了两个进程 [p.join() for p in process] # 等待两个进程依次结束 # run__mp() # 主线程不建议写在 if外部。由于这里的例子很简单,你强行这么做可能不会报错 if __name__ =='__main__': run__mp() # ...
import pytest def test_function(): # 执行一些测试操作 assert True def test_pytest_main(): with pytest.raises(SystemExit): pytest.main(["-x", "test_module.py"]) 这个示例中,test_pytest_main()测试函数确保pytest.main()会引发SystemExit异常。 融合pytest.main() 和自定义 fixtures 在Pytest中,...
C:>python >>>import Test >>>Test.__name__ #Test模块的__name__ 'Test' >>>__name__ #当前程序的__name__ '__main__' 无论怎样,Test.py中的"__name__ == '__main__'"都不会成立的! 所以,下一行代码永远不会运行到! 第一部分: ...
