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 and 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 letter grade 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 data input, your output should look EXACTLY like in the below table showing a few sample runs for you to compare, the items shown after the : and symbols are what you enter as input; those items can vary for each sample run): 1. 2.

The first thing you should enter in your python program script file (CH9LastFirst.py file created in step 2) is a top comment block which includes the following: Name: Enter your full name here Lab: Chapters 9 Description: This needs to be at least a paragraph explanation of the program (in your own words) b. Below the top comment block, type the actual python code for the problem described in step 3. Make sure to include the functions as described below EXACTLY! (Refer to the sample code screenshot below with function calls and definition examples and HINTS): a. main() This main function should define the variables required and call the below functions (Refer to HINTS in line #ts b. Below the top comment block, type the actual python code for the problem described in step 3. Make sure to include the functions as described below EXACTLY! (Refer to the sample code screenshot below with function calls and definition examples and HINTS): a. main() This main function should define the variables required and call the below functions (Refer to HINTS in line #s 14 - 19 in the below sample program screenshot) b. fill_grade_book() This should be a value returning function called by main() function, that accepts no arguments. This function will accept from the user the number of students to add to the gradebook. Then, prompt for each student's name and letter grade and create a dictionary-based gradebook and returns the dictionary back to the main function (Refer to HINTS in line #s 23 - 31 in the below sample program screenshot) c. count_letter_grades() This should be a value returning function called by main function, that accepts one dictionary argument. The program should then count the number of similar grade letters made by students and store them in a counter list for different letter grades and return the list back to the main function (Refer to HINTS in line #s 33 - 40 in the below sample program screenshot) d. display_grade_report() This should be a void function called by main function that accepts one list argument that has the counts of similar grade letters and displays them as shown in the above output/results screenshots (Refer to HINTS in line #s 42-46 in the below sample program screenshot) Make sure to include the following in your program as well: i. Define appropriate/descriptive CONSTANTS/variable_names (Refer to line #s 8-12, 16-17, etc. in the below screenshot for examples) ii. Have enough documentation for understandability of your program by including a comment block at the beginning of the program (Refer to line #s 1 - 8 in the below screenshot) and prior to each function describing in your own words the purpose of each function by explaining the logic of loop, if, and other python functions used (refer to Textbook/Instructor EXAMPLE PROGRAMS listed in Canvas Modules) iii. Have proper indentation and line spacing for readability of your program (refer to Textbook/Instructor EXAMPLE PROGRAMS listed in Canvas Modules) CH9RaoSuma.py .
