Study 2 —— 格式化输出

打印人物信息的两种方法
第一种：

Name = input('Input your name: ')
Age = input('Input your age: ')
Job = input('Input your job: ')
Hometown = input('Input your hometown: ')

print('---------- Info of', Name,'----------')
print('Name:	', Name)
print('Age: ', Age)
print('Job: ', Job)
print('Hometown: ', Hometown)
print('------------- End -------------')　

 

第二种：

Name = input('Input your name: ')
Age = input('Input your age: ')
Job = input('Input your job: ')
Hometown = input('Input your hometown: ')

info = '''
---------- Info of %s ----------
Name:	   %s 
Age :	   %s 
Job :	   %s 
Hometown:  %s 
-------------- End -------------
''' % (Name, Name, Age, Job, Hometown)

print(info)

　　

两种方法实现的结果都如下所示：

C:\Users\Administrator\Desktop>python info.py
Input your name: Lisa
Input your age: 18
Input your job: modal
Input your hometown: UK

---------- Info of Lisa ----------
Name:       Lisa
Age :       18
Job :       modal
Hometown:   UK
-------------- End ------------- 

　　

注：第二种方法是将人物信息进行格式化输入输出，更加方便. %s是占位符
%s 　　字符串(string)
%d　　 数字(digit)
%f 　　 小数(float)

所以上面的代码还可以这样写：

Name = input('Input your name: ')
Age = int(input('Input your age: '))
Job = input('Input your job: ')
Hometown = input('Input your hometown: ')

info = '''
---------- Info of %s ----------
Name:	   %s 
Age :	   %d 
Job :	   %s 
Hometown:  %s 
-------------- End -------------
''' % (Name, Name, Age, Job, Hometown)

print(info)
