今天朋友告诉我说终于把手机给我寄了，但是用的是USPS的first class，我的个天，只有看自己人品好不好了。写了个抓取进度的脚本。很简单。 遇到一些问题刚开始两个list循环如下：
for info,date in infos, dates:
print “%s @ %s” % (info.text, ‘ ‘.join(date.text.split()))
会失败报错ValueError: too many values to unpack 想了下可以直接用index指定输出内容呀！(真傻还想了一会儿才想到)于是该了一下成这样
for i in range(len(track_date)):
print “%s @ %s” % (track_info[i].text,track_date[i])
这里重要的是track_info[i].text里的.text 才会提取内容，不然html的tag都一并输出了这就不友好了。
