computer science help

I need them with ditails of each step in comments # python


#a. Write a function countValue that accepts FOUR parameters: two-dimensional list of 
#integers,  row and col (sizes of the list) and the additional integer. The function returns 
#the amount of times that integer appears in the list. 

#b. Write a program  that inputs sizes of 2d list,  
#randomly generates TWO two-dimensional lists 
#of integers between 0 and 5, and generates additional integer between 1 and 5 to search for. 
#The program finds the number of times that integer appears in each 2d list.

#The program is partially written for you. Complete the program

import random

def countValue(my_list, row, col, num):
#complete this function

def make_list(scores, row, col):
        for i in range(row):
                for j in range(col):

                        scores[i][j]=random.randint(0,5)
        return scores

def printMatrix(scores, row, col):
        for i in range(row):
                print(scores[i])

def main():
#complete the main


main()
