Python模拟登陆淘宝并统计淘宝消费情况的代码实例分享

支付宝十年账单上的数字有点吓人，但它统计的项目太多，只是想看看到底单纯在淘宝上支出了多少，于是写了段脚本，统计任意时间段淘宝订单的消费情况，看那结果其实在淘宝上我还是相当节约的说。
脚本的主要工作是模拟了浏览器登录，解析“已买到的宝贝”页面以获得指定的订单及宝贝信息。

使用方法见代码或执行命令加参数-h，另外需要BeautifulSoup4支持，BeautifulSoup的官方项目列表页：https://www.crummy.com/software/BeautifulSoup/bs4/download/

首先来说一下代码使用方法:

python taobao.py -u USERNAME -p PASSWORD -s START-DATE -e END-DATE --verbose

所有参数均可选，如:

python taobao.py -u jinnlynn 

统计用户jinnlynn所有订单的情况

python taobao.py -s 2014-12-12 -e 2014-12-12

统计用户(用户名在命令执行时会要求输入)在2014-12-12当天的订单情况

python taobao.py --verbose

这样就可以统计并输出订单明细。

好了，说了这么多我们就来看代码吧：
