Average of Numbers with Exception Handling

Assume that a file containing a series of integers is named numbers.txt and exists on the computers disk. Download this file which is attached. Write a program that calculates the average of all the numbers stored in the file. Make sure that the program should ask a file name to read. Modify the program that you wrote so it handles the following exceptions:

It should handle any IOError exceptions that are raised when the file is opened and data is read from it.

It should handle any ValueError exceptions that are raised when the items that are read from the file are converted to a number. Check and fix the file by removing non-numeric data. There are two non-numeric data cat and dog.
