Technology evolves constantly. People are constantly looking for tools that will allow them to solve their problems more easily than before. Every few months, either a completely new language pops up almost out of nowhere, or one of the well-established languages introduces a completely new syntax feature. This also happens to Python. We will briefly consider a few of the most important recent additions to the Python language in Chapter 3, New Things in Python.

New languages or language features drive the creation of novel libraries and frameworks. These in turn open the way for new programming paradigms and new design patterns. The success of one such pattern or paradigm in one language ecosystem often encourages programmers to adopt them in other languages. That's how new ideas spread from language to language.

We see that happening to Python too. We will be able to see how seemingly different programming languages share similar features or...
