## 一.Python 计算总分数和平均分源码 ##

有位小粉丝后台公众号后台留言，需求是使用 [Python][Python 2] 从键盘上输入学生的姓名，语文数学英语成绩，计算平均分和总分，然后输出这个学生的姓名，平均分和总分，源码如下：

# !usr/bin/env python
    # -*- coding:utf-8 _*-

    """
    
    def main():
    
        # 数学成绩
        maths_score = 0
        # 英语成绩
        english_score = 0
        # 姓名
        name = input("请输出姓名：")
    
        while True:
    
            # 增加异常处理，当输入不是纯数字的时候，提醒输入错误
            try:
                # input 的默认返回值是 str字符串类型，需要通过float强制转换一下
                maths_score = float(input("请输入数学成绩："))
                english_score = float(input("请输入英语成绩："))
                break
            except:
                print("输入错误，分数请用数字表示....")
    
        print("你输入的姓名是：%s 总分：%d 平均分：%f "%(name,maths_score+english_score,(maths_score+english_score)/2.0))
    
    
    if __name__ == "__main__":
        main()
    
    '''
    测试结果：
    
    请输出姓名：熊孩子
    请输入数学成绩：DF
    输入错误，分数请用数字表示....
    请输入数学成绩：45
    请输入英语成绩：FDF
    输入错误，分数请用数字表示....
    请输入数学成绩：45
    请输入英语成绩：78
    你输入的姓名是：熊孩子  总分：123 平均分：61.500000
    
    '''

程序中加了 [**try except 异常处理**][try except]，避免用户在输入错误的时候程序异常崩溃退出，这样可以增加程序的健壮性；源码没几行，比较简单，小鲜肉加油~~
