The Compulsory Features List

One way to describe a language is by listing its features. Of course, this will be more meaningful after you've seen Python in action; the best I can do now is speak in the abstract. And it's really how Python's features work together, that make it what it is. But looking at some of Python's attributes may help define it; Table 1-1 lists some of the common reasons cited for Python's appeal.

Table 1-1. Python Language Features

Features

May be freely embedded and shipped

To be fair, Python is really a conglomeration of features borrowed from other languages. It includes elements taken from C, C++, Modula-3, ABC, Icon, and others. For instance, Python's modules came from Modula, and its slicing operation from Icon (as far as anyone can seem to remember, at least). And because of Guido's background, Python borrows many of ABC's ideas, but adds practical features of its own, such as support for C-coded extensions.
