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 应用程序来自动执行内部任务，并使用自定义 GUI 交互式地指导用户。
Creo 提供了一个 Java API，它对不同的函数有相当不错的覆盖，而 VB API 则较弱。 Polyworks SDK“使用 Microsoft 的 COM 架构来实现大部分功能（还通过纯 C++ API 提供附加功能）”。
在 Creo 中 - 我已经成功执行了与使用 VB、Java、VBA 的程序交互的示例程序，并通过调用用 Python 生成的内部宏语言文件（跟踪文件）。
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技巧感兴趣？或者说这样做是否会导致效率极低？
重要的第一步是什么？创建一个函数库，记录函数的正常用法和嵌套，然后开始编写调用 Python 中创建的不同模块的脚本？
预先感谢您的任何建议。
只是为了让它更真实：
