In Python code: Write a function to convert a integer to hexidecimal. Do not use the Python hex function (i.e. hexnumber = hex(number)) to convert the number, instead write your own unique version (i.e. MYHEX: hexnumber = MYHEX(number)). Your function should not use any Python functions like hex, dec, oct, bin or any other Python functions or modules. Functions, like Python ORD, can be used to convert a string to a integer.
Write a function count_evens() that has four integer parameters, and returns the count of parameters where the value is an even number (i.e. evenly divisible by 2). Ex: If the four parameters are: 1 22 11 40 then the returned count will be: 2 Hint: Use the modulo operator % to determine if each number is even or odd. Your program must define the function:count_evens(num1, num2, num3, num4) python # Define your function here if __name__ == '__main__': num1 = int(input()) num2 = int(input()) num3 = int(input()) num4 = int(input()) result = count_evens(num1, num2, num3, num4) print('Total evens:', result)

Because these tasks surface in many problems, design a general set of functions you can reuse in other programs. • The problem is described and analyzed in the lecture slides. You will prompt a user to enter some numbers that you will accumulate, find their sum and average. You will rely on the functions in the accompanying figure to accomplish this. You will display the sum and average of these numbers before you exit the program. Upload a file with the source code of your program after you have tested it.
