python3.5中的格式化输出

运用占位符来进行格式化输出

代码如下：

#__ author:"Cheng"
#date:2018-02-12

name = input("请输入您的姓名：")
age = input("请输入您的年龄：")
job = input("您的工作：")
salary = input("您的薪资是多少：")


if age.isdigit():
    age = int(age)
else:
    exit("年龄请输入数字！")

age_tuixiu = 1
if age == 65:
    age_tuixiu = "您今年退休！"
elif age > 65:
    age_tuixiu = "您该退休啦！"
else:
    age_tuixiu = '您还有'+str(65-age)+'年退休！'

if salary.isdigit():
    salary = int(salary)
else:
    exit("薪资请输入数字！")

msg2 = "薪资"
if salary >= 10000:
    msg2 = "工资这么高啊！"
elif salary >= 4000:
    msg2 = "工资一般吧！"
else:
    msg2 = "工资也太低了吧！"

msg = '''

---------- info of %s ----------
姓名：%s
年龄：%s
工作：%s
薪资：%s (%s)
%s
---------- end ----------

'''%(name,name,age,job,salary,msg2,age_tuixiu)

print(msg)

输出结果：

%s 字符占位符 string

%d 数字占位符 digit

%f  符点数(相当于小数) float
