但是，在大多数情况下，启动和使用外部进程，是一个非常糟糕，非常有限的方法。您几乎无法控制生成过程，因此这种方法主要限于仅使用控制台的应用程序从命令行获取输入并将输出放在标准控制台或某些文件中。更好的方法是使用Python应用程序的库（DLL）。如何做到这取决于特定的Python实现;一些提供与本机DLL的互操作性，一些使用.NET程序集...

However, starting and using of external process, in most cases, is a pretty bad, very limited approach. You get almost no control over the spawn process, so this approach is mostly limited to console-only application taking input from a command line and putting the output in a standard console, or some files. Much better approach would be using the library (DLL) by a Python application. How to do it depends on the particular Python implementation; some provide interoperability with native DLLs, some work with .NET assemblies…
