Write a function named calculatescores that takes two parameters, an input file name and an output file name. The input file has only one column of scores. The function calculatescores will read in the scores from the file and write their count, total, and average into the output file. Your program should prompt the user to enter an input and an output filename. Here is a sample run:

Please enter the input file name: scores.txt Please enter the output file name: scores.out 

The scores.txt has unspecified number of scores and extra blank lines in the file:

100 90.5 95 <-- blank line 80.2 40.5 <-- blank line <-- blank line  <-- more scores 

After you calculate the number of scores, total, and average from the input file, write the results to the output file using the string format. Remember, dont count the blank lines in the input file. Your output file should look like the following:

There are 5 scores The total is 406.20 The average is 81.24 

You will use the main level script section to separate your input statements and function call from the function definition. Use string format to format the total and average to two decimal places. Your program should work for any input file and not just the one as shown here. I will test your program with a different file.
