比如
L = [{"name": "zhangsan", "birth":19920208, "gender":"m"}, {"name": "lisi", "birth":19900609, "gender":"m"}, {"name": "wanghong", "birth":19950907, "gender":"f"}]
對字典排序就是對列表進行排序後打印：
from operator import itemgetter
L = sorted(L,key=itemgetter('birth'),reverse=True)
for i in range(0,len(L)):
... print("Name: {:10} Gender: {:2} Birth: {}".format(L[i]["name"],L[i]["gender"],L[i]["birth"]))
