Develop a program that will open a file named data.dat for reading ("data.dat" has been given along with the assignment in BB). This file will contain an unknown number of values that should be read in and then averaged together. The data file will be written such that each line contains 1 record. The data contained in this file should then be averaged together by using a function and the number of items and the average of the items should be printed to the screen. The file only has a lot of numbers and it is asking to create a program in phyton to get the average of all those numbers.
