New to programming? Python is free, and easy to learn if you know where to start! This guide will help you to get started quickly.

没玩过编程? Python语言是免费的,如果你知道从何处开始,它很容易上手! 本指南将帮助你快速入门。

New to Python?


Read BeginnersGuide/Overview for a short explanation of what Python is.


Getting Python


Next, install the Python interpreter on your computer.


This is the program that reads Python programs and carries out their instructions; you need it before you can do any Python programming.


There are currently two major versions of Python available: Python 2 and Python 3. The Python2orPython3 page provides advice on how to decide which one will best suit your needs. At the time of writing (21 Jun 2010), the rest of this page assumes you've decided to use Python 2.

目前Python有两个主要版本:Python 2和Python 3.通过Python2orPython3 页面提供的建议,你可以决定哪个版本最适合你。在撰写本文时(2010年6月21号),以下内容假设你决定使用Python 2。

See BeginnersGuide/Download for instructions for downloading the correct version of Python.

查看文章 BeginnersGuide/Download,按步骤下载正确的Python版本。

At some stage, you'll want to edit and save your program code. Take a look at HowToEditPythonCode for some advice and recommendations.

在某些阶段,你想编辑并保存你的程序代码。看一下 HowToEditPythonCode 以听取一些意见和方法推荐。

Learning Python


Next, read a tutorial and try some simple experiments with your new Python interpreter.


Most tutorials assume you know how to run a program on your computer.


If you are using Windows and need help with this, see How do I Run a Program Under Windows.


Once you've read a tutorial, you can browse through Python's online documentation. It includes a tutorial that may be helpful, a Library Reference that lists all of the modules that come standard with Python, and the Language Reference for a complete (if rather dry) explanation of Python's syntax.

当你读完教程后,可以浏览Python在线文档。它包括:有用的a tutoriala Library Reference详列了Python的标准库中的模块和[[|the Language Reference]介绍了Python语法的完整解释(有些枯燥)

When you are ready to write your first program you will need a text editor. To get started you can use any editor you are familiar with - even something like Notepad - but as you gain experience you may want to use a text editor with features that help you write Python programs. See PythonEditors for a list of programs friendly to Python code editing.

在准备写第一个程序前,你需要一个文本编辑器。开始时使用你任何你熟悉的编辑器-即使像Notepad记事本-但当你有经验后,你会想使用带有Python编程辅助功能的文本编辑器。参考 PythonEditors 包含了一个带有友好的Python代码编辑功能的程序列表。

Need Help?


Need help with any of this? Read BeginnersGuide/Help for mailing lists and newsgroups.

需要以下帮助吗?阅读 BeginnersGuide/Help,加入邮件列表和新闻组。

Most Python books will include an introduction to the language; see IntroductoryBooks for suggested titles.

绝大多数的Python书会包含本编程语言的介绍:查看 IntroductoryBooks中的建议标题。

Consult BeginnersGuide/Examples for small programs and little snippets of code that can help you learn.


Or, if you prefer to learn Python through listening to a lecture, you can attend a training course or even hire a trainer to come to your company.


Consult the PythonEvents page to see if any training courses are scheduled in your area, and the PythonTraining page for a list of trainers.

参考 PythonEvents 页面看在当地有无定期的培训课程,在PythonTraining页面有培训人员列表。

Teachers can join the EDU-SIG, a mailing list for discussion of Python's use in teaching at any level ranging from K-12 up to university.

老师可以加入 EDU-SIG,在该邮件列表中讨论从K-12到大学的各级别中的Python应用。
