# 第一种交互方式

name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary")
info = \'\'\'
 ---------- info of \'\'\'+name+\'\'\' -----------
 Name:\'\'\'+name+\'\'\'
 Age:\'\'\'+age+\'\'\'
 Job:\'\'\'+job+\'\'\'
 Salary:\'\'\'+salary+\'\'\'
 \'\'\'
print(name,age,job,salary)

# 第二种交互方式 %s 字符串  %d  整数   %f 浮点数  %.2f 浮点数保留两位
name = input("name:")
age = input("age:")
age = int(input("age:")) # 强制转换成int
print(type(age)) # 打印一个变量的数据类型
#print(type(str(age)))# 整型转换成字符串
job = input("job:")
salary = input("salary:")
info = \'\'\'
---------- info of %s -----------
Name:%s
Age:%s
Job:%s
Salary:%s
\'\'\' %(name,name,age,job,salary)
print(info)

第三种交互方式
name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")
info = \'\'\'
---------- info of {_name} -----------
Name:{_name}
Age:{_age}
Job:{_job}
Salary:{_salary}
\'\'\' .format(_name=name,
            _age=age,
            _job=job,
            _salary= salary)
print(info)

# 第四种交互方式
name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")
info = \'\'\'
---------- info of {0} -----------
Name:{0}
Age:{1}
Job:{2}
Salary:{3}
\'\'\' .format(name,age,job,salary)
print(info)
