can someone help me using python using that given function specifications thanks!.

Mapping score to grade Objectives: Practice function definition. Write a function to map a score to a grade based on the following table: The function should be named point_to_grade and be able to accept an integer, representing a score, as argument. It should return a character that is the grade corresponding to the input score. Function specifications: Function name point_to_grade Input parameter an integer representing a score Return value a character representing a grade For example, if input parameter is 7 5 0, then the return value should be ' B'. Testing: Develop at least 2 test cases, calculate the correct results by hand, and then confirm that your program gives the same results. To test the correctness of your function, you can make function calls, one for each of your test cases. For example, print (point_to_grade (750)) should display B on screen. When you are ready to submit, remove all such function calls from your script file. You do not need to submit your test cases. Code specifications: Your submitted .py file should contain ONLY your function definition for point_to_grade. DO NOT include your testing codes. The instructor will use his test cases for testing your function
