Deitel – Python – How to Program

Description

Most people are at least somewhat familiar with the exciting capabilities of computers. Using this textbook, you will learn how to command computers to exercise those capabilities. It is software (i.e., the instructions you write to command the computer to perform actions and make decisions) that controls computers (often referred to as hardware). Computer use is increasing in almost every field. In an era of steadily rising costs, the expense of owning a computer has been decreasing dramatically due to rapid developments in both hardware and software technology. Computers that filled large rooms and cost mi ons of dollars 25 to 30 years ago now are inscribed on the surfaces of silicon chips smaller than a fingernail and that cost perhaps a few dollars each. Silicon is one of the most abun dant materials on the earth—it is an ingredient in common sand.
