Write a python program that writes a series of random numbers to a file. Each random number should be in the range of 1 through 500. The application should let the user specify how many random numbers the file will hold. Write another program that reads the random numbers from the file, displays the numbers, then displays the following data: The total of the numbers The number of random numbers read from the file

Follow-up Question
Make the following modifications for the solution above:
- name the output/input file "myRandomNumbers.txt"
- use a loop to output 17 random numbers to the file
- after creating the file, close it
- open the file for input and read the contents and then
- total the numbers in the file
- determine the average of the numbers in the file
- determine the highest and lowest numbers in the file
- DO NOT USE PYTHON BUILTIN FUNCTIONS TO CALCULATE THE AVERAGE OR THE HIGHEST AND LOWEST NUMBERS
- an expected number of modules/functions would be in the 5-8 range
Display your results:
- the numbers generated on a single horizontal line
- the calculated total and average
- the highest and lowest number in the file
Be sure to use clear prompts/labeling for input and output.
