if __name__ =='__ main__'不工作ipython [英] if __name__ == '__main__' not working ipython

问题描述

我无法获取如果__name =='__ main __'技巧在IPython，Spyder环境中工作。我尝试过这个帖子中给出的每一种方法：
if __name__ =='__ main__'在IPython中

I'm having trouble getting the if __name == '__main__' trick to work in an IPython, Spyder environment. I've tried every approach given in this thread: if __name__ == '__main__' in IPython

这是我的超级简化模块

Module1.py

Module1.py

Class UnitTest():
    print 'Mod1 UnitTest!'

if __name__ == '__main__':
    UnitTest()

Module2.py

Module2.py

import Module1

Class UnitTest():
    print 'Mod2 UnitTest!'

if __name__ == '__main__':
    UnitTest()

所以我运行Module2.py而且我总是看到 Mod2 UnitTest 和 Mod1 UnitTest 已打印。这些是在IPython内核中执行的。我只想显示 Mod2 UnitTest 消息。

So I run Module2.py and I always am seeing both Mod2 UnitTest and Mod1 UnitTest printed. These are executing in an IPython kernel. I want only the Mod2 UnitTest message to display.

知道怎么回事？

推荐答案

我之前因为尴尬而删除了这个问题，但是如果其他任何新手都看到这个问题，也可以分享。

Well I deleted this question earlier out of embarrassment but might as well share in case any other newb sees this.

我忘记将UnitTest行放在 __ init __ 方法中。因此，在定义类时每次运行单元测试，而不是在实例化对象时运行。代码应为：

I forgot to put the UnitTest line inside of the __init__ method. So the unit test was being run every single time when the class was defined and not when the object was instantiated. The code should be:

Module1.py

Module1.py

Class UnitTest():
    def __init__(self):
        print 'Mod1 UnitTest!'

if __name__ == '__main__':
    UnitTest()

Module2.py

Module2.py

import Module1

Class UnitTest():
    def __init__(self):
        print 'Mod1 UnitTest!'

if __name__ == '__main__':
    print 'Mod2 UnitTest!'
