class Teacher:

for key in data.keys():

我想按age排序或者按赋值的顺序排序，请问下要怎么实现？初学者，请各位前辈赐教，谢谢

可以使用内置函数sorted排序。

import operator

class Teacher:
    def __init__(self):
        self.age = "";
        self.name = u"";
        self.salary = "";

data = dict();
data["t"] = Teacher();
data["t"].age = 33;
data["t"].name = "liu";
data["t"].salary = "4000";
 
data["s"] = Teacher();
data["s"].age = 11;
data["s"].name = "liang";
data["s"].salary = "85";
    
data["d"] = Teacher();
data["d"].age = 20;
data["d"].name = "li";
data["d"].salary = "85";


result = sorted(data.values(), key = operator.attrgetter('age'))
for teacher in result:
    print "-------------------"
    print "name:", teacher.name
    print "age:", teacher.age
    print "salary:", teacher.salary

实现了，谢谢^^。先处理任务，回头再深入看下

def sortDic(Dict):return sorted(Dict.items(),key=lambda a:a[1])

sorted(data.values(),key=lambda x:x.age)
