3 以%形式
4
5 #输入用户基本信息，然后再输出来
6
7 name = input("Name:")
8 age = int(input("Age:")) #int转换为数字类型，不然出错 年龄为整数啊
9 print(type(age）#tpye一下看看age变量的数据类型
10 job = input("Job:")
11 money = int(input("Money:"))
12 info ='''
13 ----------info of (%s)----
14 Name:%s
15 Age:%d
16 Job:%s
17 Money:%s
18 '''%(name,name,age,job,money)
19 print(info)
20
21 以 .format形式输出信息
22 name = input("Name:")
23 age = int(input("Age:"))
24 job = input("Job:")
25 money =input("Money:")
26 info ='''
27 ----------info of {0}-------
28 Name:{0}
29 Age:{1}
30 Job:{2}

32 '''.format(name,age,job,money)
33 print(info)
34
35 以更高形式的.format形式输出用户信息
36 name = input("Name:")
37 age = int(input("Age:"))
38 print(type(age))
39 job = input("Job:")
40 money = input("Money:")
41 info ='''
42 ----------info of {name}-------
43 Name:{name}
44 Age:{age}
45 Job:{job}
46 Money:{money}
47 '''.format(name=name,
48 age=age,
49 job=job,
50 money=money)
51 print(info)

55 count = 0
56 while num < 3:
57 usename = input("username:")

59 if usename == _usename and password == _password:
60 print("welcome,",usename)
61 break
62 else:
63 print("the usename or password is wrong")
64 count = count + 1
65 continue
