- 什么是python？

Python is an elegant and robust programming language that delivers both the power and general applicability of traditional compiled languages with the ease of use (and then some) of simpler scripting and interpreted languages. It allows you to get the job done, and then read what you wrote later. You will be amazed at how quickly you will pick up the language as well as what kind of things you can do with Python, not to mention the things that have already been done. Your imagination will be the only limit. Work on Python began in late 1989 by Guido van Rossum, then at CWI (Centrum voor Wiskunde en Informatica, the National Research Institute for Mathematics and Computer Science) in the Netherlands. It was eventually released for public distribution in early 1991. How did it all begin? Like C, C++, Lisp, Java, and Perl, Python came from a research background where the programmer was having a hard time getting the job done with the existing tools at hand, and envisioned and developed a better way. At the time, van Rossum was a researcher with considerable language design experience with the interpreted language ABC, also developed at CWI, but he was unsatisfied with its ability to be developed into something more. Having used and partially developed a higher-level language like ABC, falling back to C was not an attractive possibility. Some of the tools he envisioned were for performing general system administration tasks, so he also wanted access to the power of system calls that were available through the Amoeba distributed operating system. Although van Rossum gave some thought to an Amoeba-specific language, a generalized language made more sense, and late in 1989, the seeds of Python were sown. Although it has been around for well over fifteen years, some feel that Python is still relatively new to the general software development industry. We should, however, use caution with our use of the word “relatively,” as a few years seem like decades when developing on “Internet time.” When people ask, “What is Python?” it is difficult to say any one thing. The tendency is to want to blurt out all the things that you feel Python is in one breath. Python is (fill-in-the-blanks here) . Just what are some of those features? For your sanity, we will elucidate each here . . . one at a time.
