python，从模块调用函数的麻烦 [英] python, trouble with calling functions from a module

问题描述

我导入了一个模块如下：

I imported a module as below:

filename = "email"
mymodule = __import__('actions.'+filename)

我遇到的问题是，文件是立即执行的，而我更愿意从文件中执行特定的功能（这样我可以通过它发送变量）。

the problem I have with this is, that the file is immediatly executing, and I would much rather execute a specific function from the file (that way I can send variables through it).

我基本上使用插件，所以它可以工作。

I am basically working with plugins, so it works.

编辑：暂时是
，我不关心当我添加以下行时脚本是否执行：

Edit: for the time being, I am not concerned with whether or not the script executes when I add the line below:

mymodule = __import__('actions.'+filename)

但我想要工作的是当我在下面添加这一行时，我希望该函数能够执行。但相反，我得到一个错误，模块没有该功能，即使它在脚本中存在。

but what I would like to work is when I add the line below, I would like the function to execute. But instead I get an error that the module dosn't have that function even though it exisits in the script.

mymodule.dosomething(n)

编辑：
我个人不知道认为该函数与它有任何关系，但这里有一个我试图打开的python文件。

Edit: I personally don't think that the function has anything to do with it but here is one python files that I am trying to open.

import webbrowser
def OpenEmail():
    handle = webbrowser.get()
    handle.open('http://gmail.google.com')
OpenEmail()
print "Your email has been opened"

推荐答案

除非模块执行，否则不存在。你不可能两种方式。也许您需要在模块中添加主要节目。

The functions don't exist unless the module executes. You can't have it both ways. Perhaps you need to add a main stanza to the module.
