Why should you learn to write programs?<\/h4>\n

Writing programs<\/a> (or programming) is a very creative and rewarding activity. You can write programs for many reasons ranging from making your living to solving a difficult data analysis problem to having fun to helping someone else solve a problem. This book assumes that everyone needs to know how to program and that once you know how to program, you will figure out what you want to do with your newfound skills.<\/p>\n

We are surrounded in our daily lives with computers ranging from laptops to cell phones. We can think of these computers as our \u201cpersonal assistants\u201d<\/a> who can take care of many things on our behalf. The hardware in our current-day computers is essentially built to continuously ask us the question, \u201cWhat would you like me to do next?\u201d.<\/p>\n

Programmers add an operating system and a set of applications to the hardware and we end up with a Personal Digital Assistant that is quite helpful and capable of helping many different things.<\/p>\n

Our computers are fast and have vast amounts of memory and could be very helpful to us if we only knew the language to speak to explain to the computer what we would like it to \u201cdo next\u201d. If we knew this language we could tell the computer to do tasks on our behalf that were repetitive. Interestingly, the kinds of things computers can do best are often the kinds of things that we humans find boring and mind-numbing.<\/p>\n

For example, look at the first three paragraphs of this chapter and tell me the most commonly used word and how many times the word is used. While you were able to read and understand the words in a few seconds, counting them is almost painful because it is not the kind of problem that human minds are designed to solve. For a computer the opposite is true, reading and understanding text from a piece of paper is hard for a computer to do but counting the words and telling you how many times the most used word was used is very easy for the computer: python words.<\/p>\n

Our \u201cpersonal information analysis assistant\u201d quickly told us that the word \u201cto\u201d was used sixteen times in the first three paragraphs of this chapter. 5 This very fact that computers are good at things that humans are not is why you need to become skilled at talking \u201ccomputer language\u201d. Once you learn this new language, you can delegate mundane tasks to your partner (the computer), leaving more time for you to do the things that you are uniquely suited for. You bring creativity, intuition, and inventiveness to this partnership.<\/p>\n","protected":false},"excerpt":{"rendered":"
