First, to submit your program as Text Entry, follow the steps below Padlord (CH9) Program Assignment Instructions Last Chard. 1/1/2021 Read and follow the directions below.carefully and perform the steps in the order listed. You will be solving one programa instructed and turning in your work electronically via an uploaded file within Eagle Online/Canvas and copy paste the program to the Text Entry box as well. Make sure and check your work prior to uploading the assignment [Print this instruction sheet if needed). Instructions 1. Using Python IDLE, create a New Empty Script File in your working drive. Note: refer to (SET) How to Download Install and Use Python IOLE Ink (Page 8 within module 2 on how to create o script file (NOTE: PLEASE MAKE SURE TO CREATE A SCRIPT FILE WITH PYTHON PROGRAM AND NOT RUN PROGRAM IN INTERACTIVE MODE AND SUMBITIM 2. Save the file with the name CH9LastFirst.py, making sure to know where you saved it, where Last and First is your actual Lastname and Firstname Reminder: You don't need to add the .py extension, IDLE will automatically add the extension) 3. You will develop a Letter Grade Counter Program as described below: a. In this modular program (using functions), you will create a dictionary-based gradebook with student's name an letter grade as key-value pair. You will then count the number of similar grade letters (A, B, C, D, and F) Initialized in a list and display a report as shown in the screenshots below). Firstly, you will accept from the user the number of students to add to the gradebook. You will then prompt for each student's name and better grad and create a dictionary-based gradebook. The program should then count the number of similar grade letters made by students and display a report as shown in the screenshot below: (NOTE: Other than the doto input, your output should look EXACTLY Nike in the below table showing a few sample runs for you to compare the items shown ofter the and symbols are what you enter as input; those items can vary for each sample run): 2. 1 to the gre
