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.

Acomputer is a multipurpose device that accepts input, processes data, stores data, and produces output, all according to a series of stored . the processing unit of most modern computers is a(n) . the instructions that tell a computer how to carry out a task are referred to as computer , which are distributed as software. computers run three main types of software: software, system software, and development tools. an example of system software is a computer system, which is essentially the master controller for all the activities that a digital device performs. digital devices are constructed using tiny electronic components that represent data bits as electrical signals. the system unit houses the system board, which contains several circuits made from semiconducting materials. computers come in three popular form factors: component, , and slate. many of today's digital devices operate on battery power supplied by ion batteries. battery life and lifespan can be extended by following good battery management practices.
