Python Learning Day 1th: hello,python!

Today is the first day to learn Python, first of all to do a brief introduction of Python, Baidu Encyclopedia under:

And then we'll talk.

First, why use Python?

1, the use of software engineers, of course, is used to write a program to do the development

2, System engineers, with Python management system, so that their work to be liberated and more like their work

Ii. what are the advantages and benefits of working with Python?

1, Python programming is very simple and very useful

2, Python is a language that will not be forgotten (I think this is the same as that), anyway, I think so far very cute very good ~650) this.width=650; "Src=" http://img.baidu.com/hi/jx2/j_0028. GIF "alt=" J_0028.gif "/>

3, Python almost allows you to do anything on the computer (of course, each language has its most suitable field, here omit 10,000 words 650) this.width=650; "Src=" http://img.baidu.com/hi/jx2/j_0058. GIF "alt=" J_0058.gif "/>)

4, Python makes you easy to earn a high salary, haha, this is also I finished learning Python after the work in the future to get!

Third, install Python

So where are we going to find python?

1. Official website: www.python.org

2. On any Linux system (recommended this method, I am learning the following process through Linux)

3.PythonXY, Portable Python This is a more portable version

Now let's write our first Python program! go,go,go~~

1, we first check the version of the Python installed in my system, its version is currently divided into 2.7.X and 3.4.X two versions, as to which to decide, for beginners not much difference (personal understanding), Because my Ubuntu system's SSH service may not be configured to connect to it with Xshell, it is demonstrated directly in the virtual machine.

One of the benefits of entering Python's interactive environment is that you can write a statement immediately to see the results of the execution

Go directly to the terminal under the Python, you can see that my system is 2.7. Version 6

Today we'll show you the output in this environment "hello,python! ", and then how to write code in the file, then today this is simple, direct input: print ' hello,python! ', and then press ENTER to see the result 650) this.width=650;" src= "http// Img.baidu.com/hi/jx2/j_0028.gif "alt=" J_0028.gif "/>
