Intro to python

Chapter 6 Solution

read_file = open('numbers.txt', 'r') file_numbers = read_file.read() read_file.close() list_values = file_numbers.split() list_length = len(list_values)

for i in range(list_length): list_values[i] = float(list_values[i])

List_sum = sum(list_values)

Average_value = (List_sum)/list_length

print(Average_value)

Problem:

Modify the program you wrote for Chapter 6 Exercise 6 so it handles the following exceptions: It should handle IOError exceptions that are raised when the file is opened and data is read from it by printing "Trouble opening file. Try again." and not executing any more of the code. It should handle any ValueError exceptions that are raised when the items that are read from the file are converted to a number by printing "File must have only numbers. Try again." and not executing any more of the code.
