The program will ask for the user to enter file name of the text file. The program will read each line of numbers, use the split() function to put the numbers in lists. For each line of numbers, the program will calculate the total of the numbers, the average value, the smallest number, and the largest number. For each line of numbers, it will then display each number, the total, average, smallest number, and the largest number. The numbers are in a text file named numbers.txt and contains the following: 1.0, 2.0, 3.0 4.0, 3.0, 2.0, 1.0 5.0, 5.0, 5.0, 5.0, 5.0arrow_forward
