itertools - 标准库之一
1. 创建无限迭代器 itertools.count(1),以1为间隔的等差数列
2. 创建无限迭代器 itertools.cycle('ABC'), 以ABC为循环的数列
3. 创建有限迭代器 itertools.repeat('A',10), 循环A 10次
4. 可以通过takewhile截取
比如 n= itertools.count(1)
ns = itertools.takewhile(lambda x: x<10, n)
5. chain()可以将2个迭代器连起来：

Python3基础知识9（模块与包简单概念）
（1）模块
#简单来讲：一个.py文件就称之为模块（Module）
注意：模块名就是py文件名（不包括.py） 比如test.py
模块化的好处：
#1、以库（比如selenium库）形式封装功能，方便给别的代码调用；
库其实就是模块和包
可以使用自己写的库，Python标准库，第三方库
#2、避免变量名冲突（包括函数名）
如果一个代码文件特别的大，变量的名字容易发生重复
需要想出不同的变量名或者函数名
如果采用模块分割代码，每个模块文件代码都不是很多，就可以大大的缓解这个问题
每个模块中的变量名作用域只在本模块中
（2）函数的调用
