Number File | Python Fiddle

#Declare variables to hold the file name and access mode
fileName = "numList.dat"
accessMode = "w"

#Open the file for writing
myFile = open(numList, accessMode)

#Write the guest names and ages to the file

#The file is a string of numbers
myFile.write("This data file contains a list of integers 0-9\n")
myFile.write("The numbers are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,\n")

#Close the file
myFile.close()

#import the csv library which contains functions to help you work with CSV files
import csv

#Declare variables to hold the file name and access mode
fileName = "numList.dat"
accessMode = "r"

#open the file 
with open(fileName, accessMode) as myCSVFile:
    #Read the file contents 
    #specify that we are using a comma to separate the values in the file
    dataFromFile = csv.reader(myCSVFile, delimiter =",")

#Create a for loop that will run once for each row in the list
    for row in dataFromFile :
        #print an entire row at a time in a list format
        print(row)

#print the entire row separating the values in the list with a comma
        print (', '.join(row))

#Print each indivudal value in each row
        for value in row :
            print(value + "\n")

#Close the file
myCSVFile.close()
