In this chapter, we discussed the elements of event-driven programming. We started from the most common examples and applications of event-driven programming to better introduce ourselves to this programming paradigm. Then, we precisely described the three main styles of event-driven programming that is callback-based style, subject-based style and topic-based style. There are many event-driven design patterns and programming techniques, but all of them fall into one of these three categories. The last part of this chapter focused on event-driven programming architectures.
As we are nearing the end of this book, you have probably noticed that the farther we go, the less we actually speak about Python. In this chapter, we have discussed elements of event-driven and signal programming, but we have barely talked about Python itself. We have, of course, discussed some examples...
