1、Python很有名，但是一直没在实际项目中用过，今天花30分钟学习下。

去Python官网

2、2.X与3.X版本相差比较大，新手用最新的3.6.4。

3、下载安装。

4、安装BeautifulSoup,CMD进入C:\Users\xxx\AppData\Local\Programs\Python\Python36-32\Scripts，运行 pip install bs4.

5、桌面建一个记事本test.py，去网上找例子，注意3.x与2.x语法不一样下面代码是3.x下可以使用的。

#!/usr/bin/python  # -*- coding: utf-8 -*-  from bs4 import BeautifulSoup  import  urllib.request  url = r'http://douban.com'  res = urllib.request.urlopen(url)  html = res.read().decode('utf-8')   html_doc = """   
The Dormouse's story
 
Once upon a time there were three little sisters; and their names were Elsie, Lacie and Tillie; and they lived at the bottom of a well.
 
...
 """    #获取BeautifulSoup对象并按标准缩进格式输出，下面用html,或者html_doc一个是本地，一个是远程。  soup = BeautifulSoup(html,"html.parser")  print(soup.prettify())  print(soup.title)

6、右键Edit with IDE,Run、Run Moudle，输出结果了吧，入门就这么简单。
