不是一股冲动就学，学得时候也不急着立马撸出代码。以下我觉得在学之前需要简单了解的！

What is Python good for?

Python is a high-level general-purpose programming language that can be appliedto many different classes of problems.

The language comes with a large standard library that covers areas such asstring processing (regular expressions, Unicode, calculating differences betweenfiles), Internet protocols (HTTP, FTP, SMTP, XML-RPC, POP, IMAP, CGIprogramming), software engineering (unit testing, logging, profiling, parsingPython code), and operating system interfaces (system calls, filesystems, TCP/IPsockets). Look at the table of contents forThe Python Standard Library to get an ideaof what’s available. A wide variety of third-party extensions are alsoavailable. Consultthe Python Package Index tofind packages of interest to you.

如官网所说，我们用python2.7.12，可以RE,Unicode，比较不同文件，网络协议等等，软件工程（单元测试，日志等等），操作系统接口，还有一堆的第三方拓展。

至于版本号的解释：

A是有重大更新才发布，B是比较小的更新较为稳定，C就是仅仅为修正bug。如果出现2.2+这样的，是不发行的版本。

Is there a newsgroup or mailing list devoted to Python?讨论组跟邮件列表

There is a newsgroup, comp.lang.python, and a mailing list,python-list. Thenewsgroup and mailing list are gatewayed into each other – if you can read newsit’s unnecessary to subscribe to the mailing list.comp.lang.python is high-traffic, receiving hundreds of postingsevery day, and Usenet readers are often more able to cope with this volume.

如果想了解python的发展态势：

What new developments are expected for Python in the future?

See https://www.python.org/dev/peps/ for the Python Enhancement Proposals(PEPs). PEPs are design documents describing a suggested new feature for Python,providing a concise technical specification and a rationale. Look for a PEPtitled “Python X.Y Release Schedule”, where X.Y is a version that hasn’t beenpublicly released yet.

New development is discussed on the python-dev mailing list.

至于python有不兼容的更新特性这个问题，官方会尽量减少带来的破坏性。

针对我没写过程序的人来说：

Python for Non-Programmers
