The history of human civilization is the history of the language, please note that I'm talking about the history of human civilization, instead of human history. Many children here is easy to understand the error prone. Yes, with the words of human language and was able to communicate, he was able to experience the history recorded. Seen how important language is a communication tool. If two people want to smooth exchange, it must be able to have a common understanding of the language. Otherwise, the exchange became howling at the moon.
So, if you want to effectively control the computer, then you have to master the necessary language to communicate with the computer, we call programming language. I remember back to high school to college after the first summer, visit our English teacher, with the teacher bragging, that I am now learning a language, called C ++ (a programming language) An almost like English s things. Later, every time I think about it, my heart would burst of laughter on. In fact, think about it, I was not blown a little cow does not make sense, English is the language of communication between human beings, and human and computer programming language is the language of communication, but the computer itself is good with words, as long as you tell it how to do just fine.
Of course, if it wants to communicate with a computer, standing on the perspective of the computer, we want to use it closer to the language of communication, so that it can better understand what we mean faster execution, also known as the efficiency It will be higher. And we naturally want to use closer to human language to communicate, so we would be easier to exchange them, but inevitable, part of the cost of the computer needs to understand human language, the efficiency will be discounted.
Language difficulty degree of efficiency close to the computer
assembly language is difficult to highest highest
c language difficult high
c ++ difficult higher higher
java generally lower low
python generally low low
From my contact with the programming language, the most close to the computer language is compiled. Of course, according to my teacher, before there is a thing called a program with a similar long roll of tape to be programmed by the top punch. To be honest, even though I'm curious about this stuff, but I never could have seen. Of course, you may be wondering, since there is a relatively simple language similar to java / python like, why use a high difficulty in developing language? The question here is not too much to discuss, you only need to know that there is a reasonable, each language has its applicable space, if in the future you can learn more in-depth programming techniques, you will have a more profound this To understanding.

Next, we will do many interesting things (including those above example code) are done with python. So then, the most exciting moment is coming in. But before you call a master or a hacker, you have to have patience to figure out the basic things, I will try to make the process seem relaxed and happy.
