Python
基础
前面你已经在计算机上安装并运行了
Python
,下面我们来学习一些
Python
的基础知识。
后续章节的内容都建立在这些概念的基础上,我们需要首先掌握这些概念。
在上一章中,我们利用下面几行代码测试了
Python
的安装是否成功:
import
sys
import
pprint
pprint.pprint(sys.path)
读完本章,你将会明白上面每一行代码的含义,并学会相关术语,能够说明上述代码的作
用。你还将学习
Python
的各种数据类型,对
Python
的入门概念有基本的了解。
我们会讲得比较快,把重点放在学习后续章节时需要知道的内容。后续章节中我们还会根
据需要讲一些新概念。我们希望这种方法能让你将这些新概念应用于感兴趣的数据集和问
题,并从中学到东西。
首先我们启动
Python
解释器。本章的
Python
代码都在解释器中运行。浏览一遍本章这样
的介绍性内容是很容易的,但我们要着重强调动手敲代码的重要性。与学习一门口语类
似,在实践中学习是最有效的学习方法。在你输入本书练习代码并运行的过程中,会遇到
大量的错误,而调试过程(解决这些错误的过程)会让你学到很多知识。
启动
Python
解释器
在第
1
章里我们学过如何启动
Python
解释器。提醒一下,你首先需要打开命令行工
具,然后输入
python
(如果你安装了附录
F
中提到的
IPython
,也可以输入
iPython
):
