Starting out with python 4th edition

Write program that lets the user enter in a file name (numbers.txt) to read, keeps a running total of how many numbers are in the file, calculates and prints the average of all the numbers in the file. This must use a while loop that ends when end of file is reached. This program should include FileNotFoundError and ValueError exception handling.

count+=1
print('There were {} numbers in the file'.format(count))
print('The average is {}'.format(sums/count))

The output is
