1.简单比较
age_dic={‘age1456‘:15,‘age2‘:16,‘xiaohong_age‘:12,‘xiaoming_age4‘:18,‘age5‘:10}
print(max(age_dic)) # key值进行比较。比较时一位一位比较
print(max(age_dic.values())) # values 值比较
运行结果：
xiaoming_age4 18 Process finished with exit code 0
2.高级方法
age_dic={‘age1456‘:15,‘age2‘:16,‘xiaohong_age‘:12,‘xiaoming_age4‘:18,‘age5‘:10}
for item in zip(age_dic.values(),age_dic.keys()): print(item) # 返回每个值 print(max(zip(age_dic.values(),age_dic.keys())))
运行结果：
(15, ‘age1456‘) (16, ‘age2‘) (12, ‘xiaohong_age‘) (18, ‘xiaoming_age4‘) (10, ‘age5‘) [18, ‘xiaoming_age4‘] Process finished with exit code 0
3.终极方法
a =[
{‘name‘:‘aa‘,‘age‘:18},
{‘name‘:‘bb‘,‘age‘:21},
{‘name‘:‘xm‘,‘age‘:10}
]
print(max(a,key=lambda dic:dic[‘age‘]))
‘‘‘
就相当于：
ret = []
for item in a:
ret.append(item[‘age‘])
print(ret)
max(ret)
‘‘‘
运行结果：
{‘name‘: ‘bb‘, ‘age‘: 21}
Process finished with exit code 0
