为什么选择
Python
有那么多种编程语言，本书为什么选择使用
Python
？你可能听说过以下这些语言中的一种
或多种：
R
、
MATLAB
、
Java
、
C/C++
、
HTML
、
JavaScript
和
Ruby
，这取决于你的专业背
景。这些语言都有一种或多种主要用途，有些还可以用于数据处理。你也可以用
Excel
等
程序进行数据处理。用
Excel
和
Python
编程，通常会得到相同的结果，但其中一种语言的
效率更高。然而有时候，像
Excel
这样的程序无法完成任务。我们选择
Python
而不是其他
语言，是因为
Python
很容易上手，处理数据的过程也简单明了。
如果你想了解
Python
和其他语言的技术性区别，可查阅附录
A
。看完里面的解释，你就
可以告诉其他分析师或开发人员你使用
Python
的原因。我们相信作为开发新人，你会从
Python
的易用性中受益，同时我们希望本书能成为你的数据处理工具箱中有参考价值的一
本书。
Python
除了上述作为语言的优点，
Python
社区还是最开放和最乐于助人的社区之一。世上
没有完美的社区，但
Python
社区为新人创造了一个良好的环境：有时会有本地的教程、免
费课堂、线下聚会等，有时还会举办大型会议，人们聚在一起解决问题并分享知识。
拥有大型社区的好处显而易见——有人能回答你的问题，有人能为你的代码或模块的结构
出谋划策，有人能让你学习借鉴，还有共享代码供你在其之上构建自己的代码。想了解更

社区因成员的支持而存在。刚开始使用
Python
时，你从社区中得到的帮助会多于你的付 ...
