mac os安装pyquery

mac已经有python 2.7了，里面也已经有easy_install了

所以可以直接：sudo easy_install pyquery即可安装html的解析pyquery

使用：

#!/usr/bin/env python# encoding: utf-8from pyquery import PyQuery as pyqimport sysreload(sys)sys.setdefaultencoding("utf-8")class CrawlPython:    def __init__(self, url):        self.url = url    def crawlW3C(self):        doc = pyq(url=self.url)        cts = doc('#leftcolumn a')        pythonTXT = open("python.txt", "w")        for data in cts:            pythonTXT.write(pyq(data).text() + '\n') #写入到文件中            print pyq(data).text()            print '\n'if __name__ == '__main__':    crawl = CrawlPython('http://www.runoob.com/python/python-object.html')    crawl.crawlW3C()
