折腾：
【未解决】自动化搜索和提取安卓游戏网站game.vivo.com.cn中游戏信息列表
期间，现在有个python的list其中每个元素都是一个dict json字典，其中有个download下载量的字段
希望通过根据下载量字段去给list排序

python dict list sort
newlist = sorted(list_to_be_sorted, key=lambda k: k['name'])
但是此处是：需要从大到小排序
newlist = sorted(l, key=itemgetter('name'), reverse=True)去试试
allAppInfoList = sorted(allAppInfoList, key=lambda k: k['download'], reverse=True)
结果：
可以的
排序前：
下载量是：
download=28602420=2860万
排序后：
可见大部分元素位置都变化了。
第一个内容是：
下载量是
download=41805393=4180万
第二个是3000万+
是对的。
【总结】
此处最后给dict的list，其中希望根据dict中download字段（int值）去由高到低排序，代码是：
allAppInfoList = sorted(allAppInfoList, key=lambda k: k['download'], reverse=True)
即可。
