The data file will be a complete list of numbers. #The program then opens the file in read mode and displays it before closing #Open the file for writing myFile = open('numList.dat','w') #Write a file that is a string of numbers myFile.write("This data file contains a list of integers 0-9\nThey follow:\n") myFile.write(" 0 1 2 3 4 5 6 7 8 9") #Close the file myFile.close() #Import csv to make files read/write user friendly import csv #Open the file with open('numList.dat','r') as myCSVFile: #Uses a comma to separate the values in the file dataFromFile = csv.reader(myCSVFile) #Create a for loop that will run once for each row in the list for row in dataFromFile: for value in row: print(value) #Close the file myCSVFile.close()
