python中类未实例化引发的报错 missing 1 required positional argument: ‘self‘

一、问题描述

自定义类直接引用自定义方法，运行报错：missing 1 required positional argument: 'self'

二、问题分析

TestMethod是自定义的类，test_01_getAuth为该类的实例化方法（self：表示实例化类后的地址ID），类未实例化直接调用TestMethod.test_01_getAuth()，导致报错

三、解决方案

1.自定义类加括号，直接调用方法

if __name__ == '__main__':TestMethod().test_01_getAuth()

2.类实例化后，实例化对象调用方法

if __name__ == '__main__':run = TestMethod()run.test_01_getAuth()
