java - 如何使用 python 应用程序（java、c++、vb api 可用）与桌面应用程序通信？

Question

我是一名机械工程师，一名编程初学者，这是我的第一篇文章 - 所以提前道歉。

我有兴趣使用 Python 补充两个不同的 Windows 桌面应用程序（Polyworks 和 Creo 5.0）中的功能。我想使用我的 python 应用程序来自动化内部任务以及使用自定义 GUI 以交互方式指导用户。

Creo 提供了一个 Java api，它很好地覆盖了不同的功能和一个较弱的 VB api。Polyworks SDK“对大多数功能使用 Microsoft 的 COM 架构（其他功能也通过纯 C++ API 提供）”。

在 Creo 中 - 我已经成功地执行了使用 VB、Java、VBA 并通过调用使用 Python 生成的内部宏语言文件（跟踪文件）与程序交互的示例程序。

我对使用 Python 通过 API 与这两个桌面应用程序进行有效通信的更一般提示感兴趣？或者人们是否会期望这样做会非常低效？

重要的第一步是什么？创建函数库，记录函数的正常用法和嵌套，然后开始编写 Python 中创建的不同模块的调用脚本？

提前感谢您的任何建议。

只是为了让它更真实：
