【后悔系列】Python使用闭包编写一个学生成绩平均统计。

def outer():
    def inner(*args):
        sum = 0
        for i in args:
            sum += i
        avg = sum/len(args)
        return avg
    return inner


if __name__ == '__main__':
    ls = []
    while True:
        grade = int(input('输入学生成绩，输入0退出：'))
        if grade == 0:
            break
        else:
            ls.append(grade)
            f = outer()
            avgs = f(*ls)
            print('平均分：', avgs)
