7.4. Conclusion

In this chapter we have learned how to build a functioning Python COM server, and a graphical client application that uses it. This approach uses each language where it's strongest: Python excels at data manipulation and object-oriented development, whereas Visual Basic allows you to build rich, commercial-quality user interfaces. From the user's viewpoint, there's no way to tell she is using Python.

In addition to building the core of an application in Python, this technique offers an easy way to add a small amount of Python functionality to existing applications. For example, if you have a large VB application and want to use a specific Python tool or library, you could wrap it with a COM server and call it from VB.
