day05_03 字符串格式化

pycharm小技巧,一般情况下都需要在代码前注释以下作者以及创建日期

但是如何让软件默认生成呢?

格式化输出

可以用占位符

%s     string的缩写

#__author:Administrator
#date:2017/9/8

name = input("Name:")
age = input("Age:")
job = input("Job:")
salary = input("Salary:")

print(name,age,job,salary)

msg = '''
-------info of %s------
Name: %s
Age: %s
JOb: %s
Salary: %s
-------end------
''' % (name,name,age,job,salary)

print (msg)

#__author:Administrator
#date:2017/9/8

name = input("Name:")
age = int(input("Age:"))
job = input("Job:")
salary = input("Salary:")
print(name,age,job,salary)

msg = '''
-------info of %s------
Name: %s
Age: %s
JOb: %s
Salary: %s
You will be retired in %s years
-------end------
''' % (name,name,age,job,salary,65-age)

print (msg)

#__author:Administrator
#date:2017/9/8

name = input("Name:")
age = int(input("Age:"))
job = input("Job:")
salary = input("Salary:")

if salary.isdigit(): #长得想不想数字,比如200d,'200'
    salary = int(salary)
else:
    print("must input digit")

print(name,age,job,salary)

msg = '''
-------info of %s------
Name: %s
Age: %s
JOb: %s
Salary: %s
You will be retired in %s years
-------end------
''' % (name,name,age,job,salary,65-age)

print (msg)

全部注释:ctrl+/

%d就表示必须输入数字

占位符:

%s    s = string

%d    d = digit 整数

%f     f = float 浮点数,约等于小数

补充修改以下以上的错误代码
