python输入输出（用户密码与格式化输出）

1、用户名和密码

方法一：

 1 # Author:yebo
 2 _username = "yebo"
 3 _password = 123
 4 
 5 username = input("username:")
 6 password = int(input("password:"))
 7 
 8 if _username == username and _password == password:
 9     print("welcome user {name}   loging......".format(name = username))
10 else:
11     print("invalid username or password!")

方法二（导入getpass模块使得输入密码时隐藏）：

 1 # Author:yebo
 2 import getpass
 3 
 4 username = input("username:")
 5 password = getpass.getpass("password:")
 6 
 7 info = '''
 8 username:{_username}
 9 password:{_password}
10 '''.format(_username = username,_password = password)
11 
12 print(info)

 

2、格式化输出：

方法一：

 1 # Author:yebo
 2 name = input("name:")
 3 age = int(input("age:"))
 4 print(type(age))
 5 job = input("job:")
 6 salary = int(input("salary:"))
 7 
 8 #格式化输出方法一
 9 info = '''
10 --------info of %s-------
11 Name:%s
12 age:%d
13 job:%s
14 salary:%d
15 ''' %(name, name,age,job,salary)

方法二：

 1 # Author:yebo
 2 name = input("name:")
 3 age = int(input("age:"))
 4 print(type(age))
 5 job = input("job:")
 6 salary = int(input("salary:"))
 7 
 8 #格式化输出方法二
 9 info3 = '''
10 -------info3 of {0}-------
11 Name:{0}
12 age:{1}
13 job:{2}
14 salary:{3}
15 '''.format (name,age,job,salary)

方法三（推荐）：

 1 # Author:yebo
 2 name = input("name:")
 3 age = int(input("age:"))
 4 print(type(age))
 5 job = input("job:")
 6 salary = int(input("salary:"))
 7 
 8 #格式化输出方法三
 9 info2 = '''
10 -------info2 of {_name}-------
11 Name:{_name}
12 age:{_age}
13 job:{_job}
14 salary:{_salary}
15 '''.format (_name = name,_age = age,_job = job,_salary = salary)
