Write your own grader

The grader‘s .py file should include a function named calc which receive two parameters(the first one is the student's answer and the last is the standard answer) and return a number from 0 to 1 as the correct rate. The .py file should placed on the same folder with run.py.

评分器的.py文件应该包含名为calc的函数作为入口函数，该函数接受两个参数，第一个是学生的答案，第二个是标准答案，并且返回一个≥0且≤1的数作为正答率。这个.py文件应该和run.py放在同一个目录下。
