Random number file writer and read

Instructions

Write a program that writes a series of random numbers to a file.

  1. The count of numbers to be generated for each execution will be randomly between 1 and 20.

  2. The actual numbers generated will be random integers between 1 and 100

  3. Each run of the program will display a message indicating the number of new numbers written to the file

  4. Each run of the program will display a message indicating the number of records read from the file

  5. You cannot count or assume to know how many records are in the file. Use the deadline method with a loop to EOF.

  6. Your file read and file write must each be functions (2 functions, one for each), and each be called from main.

  7. You must use w mode for the first write to the file and a or w mode for each time after.

  8. User will determine whether to append to existing file or write new file.

Here's what I have

import random

def main():
        more = 'y'

        while more.lower() == 'y':

                random_numbers = open('Unit 4 numbers.txt', 'w')
                NumtoBeWr = random.randint(1, 20)
                print(NumtoBeWr, 'numbers added to output file: ')

                for count in range(NumtoBeWr):
                      number = random.randint(1, 100)
                      print(number)
                      random_numbers.write(str(number) + '\n')

                random_numbers.close()

                random_numbers = open('Unit 4 numbers.txt', 'r')


                # This the code to read the file

                line = random_numbers.readline()
                number = 0
                total = 0

                while line != " ":
                        number = int(line)

                        line = line.rstrip('\n')
                        print(number)
                        total = total + int(line)
                        number = number + number
                        line = random_numbers.readline()

                        print("The total of the numbers: "+ str (total))
                        print("Total count of numbers read from file: "+ str (number))
                        more = input("Do you want to run again to write and read more numbers. (Y/N): ")
                random_numbers.close()

        print("Thank for using this program")


main()

A few problems I an having

  1. It's not adding all the number together
  2. It's not counting all the number together

Sample output for the finish program should look like this:

You should update your while loop as follows:

while line:
    number += int(line)
    total += 1
    line = random_numbers.readline().rstrip("\n")

print("The total of the numbers: " + str(total))
print("Total count of numbers read from file: " + str(number))
more = input("Do you want to run again to write and read more numbers. (Y/N): ")

That is, you should put the printing of the total counts outside of the loop. Furthermore, you should increment total by one instead of by the number in the current line to get the total numbers generated.
