Python if语句练习

编写判断成绩的程序

创建~/bin/grade.py脚本,根据用户输入的成绩分档,要求如下：

1.如果成绩大于60分,输出及格

2.如果成绩大于70分,输出良

3.如果成绩大于80分,输出好

4.如果成绩大于90分输出优秀

5.否则输出你要努力了

 

#!/usr/bin/env python

grade = int(raw_input("please enter your garde:"))

if grade >= 90:
    print "You are very good"
elif grade >= 80:
    print "You are good"
elif grade >= 70:
    print "You are not so good"
else:
    print "You need to work on"
