使用参数调用python函数并在autohotkey中获取返回值 [英] Call python function with arguments and get returned value in autohotkey

问题描述

我有一个名为server.py"的 python 脚本，里面有一个函数 def calcFunction(arg1): ... return output 如何使用参数调用函数 calcFunction 并使用autohotkey 中的返回值?这就是我想要在 autohotkey 中做的事情:

I have a python script called "server.py" and inside it I have a function def calcFunction(arg1): ... return output How can I call the function calcFunction with arguments and use the return value in autohotkey? This is what I want to do in autohotkey:

ToSend = someString ; a string
output = Run server.py, calcFunction(ToSend) ; get the returned value from the function with ToSend as argument
Send, output ; use the returned value in autohotkey

我在网上看过，但似乎没有完全回答我的问题.甚至可以做到吗?

I have looked online but nothing seems to fully answer my question. Can it even be done?

推荐答案

为了将参数发送到 Python，您可以使用 Python 脚本中的参数.您可以使用 sys 库执行此操作:

In order to send your parameters to Python, you could use arguments from within your Python script. You can do this with the sys library:

import sys
print(sys.argv[0]) # name of file
print(sys.argv[1]) # first argument
print(sys.argv[2]) # second argument...

在您的 AutoHotKey 脚本中，您可以通过在指定文件名后立即将参数添加为参数来将参数发送到 Python 脚本:

From within your AutoHotKey script, you can send parameters to the Python script by adding them as arguments right after specifying the file name:

RunWait, server.py "This will be printed as the first argument!" "This is the second!"

然后，为了将函数的输出返回给 AHK，您可以再次使用 sys 通过利用它的 exit() 函数:

Then, to get the output of the function back to AHK, you could use sys again by utilizing it's exit() function:

sys.exit(EXIT_NUMBER)

回到 AHK，您会在变量 ErrorLevel 中收到 EXIT_NUMBER.放在一起，您的代码应如下所示:

And back in AHK, you recieve the EXIT_NUMBER inside the variable ErrorLevel. Put all together, your code should look something like this:

; AHK
RunWait, server.py "%ToSend%"

# Python
sys.exit(calcFunction(sys.argv[1]))

; AHK
MsgBox %ErrorLevel%
