Some areinterested in making money creating their own programs to sell to others. Somejust like to mess
12、around and learn different things about how the computer willwork. And still others have devoted their lives to programming, making it theproduct that brings home their income each month whether they work atrepairing computers, work in a corporation to keep the computers safe, or doingsome other asp
13、ect of computer technology. When it comes to computer technology, nothing is going to be simple. Beforeyou can even get a program to work on the computer, it needs to receive theright code to make it work. There are several options for code creation that acomputer tech can choose including Java, C+
14、and Python. Here we will欢迎加入非盈利Py t h o n 编程学习交流QQ群783462347，群里免费提供500+本Py t h o n 书籍！explore a bit about Python and why it is often preferred over the other twoprogramming options. Before you are able to start using Python to take over your programming needs,it is important to start learning more a
15、bout it and all of the great benefits youwill receive when using this program. Python is a high level programming tool,which means that it is easy to use and read, even as a beginner. The philosophybehind the code is readability and it has a type of syntax that allows theprogrammer to express their
16、concepts without having pages of code along withit. Compared to using other popular codes, like Java and C+, this can makePython much easier to complete. The philosophy of this code language is simple enough to use. It believes that asimple design is so much better than a complex one and that readab

Withother options, they may have to spend a lot of time trying to get the code justright, adding in many other symbols to get it to work.
18、 But with Python, it is keptmuch simpler and you may find that it is easier to read through the lines andsee what you are doing. Some of the features that you may like with Python include:欢迎加入非盈利Py t h o n 编程学习交流QQ群783462347，群里免费提供500+本Py t h o n 书籍！ An elegant syntax which will make the programs so

If you are doing ad hoc programming tasks or prototypedevelopment because it works well without issues with maintaining theprogram.Has a large library that will work with other programming tasks such ascha
20、nging files, searching for text, and connecting with web servers.Python is really interactive. This makes it easier for you to test out smallbits of code to see if they work. You can also bundle it with adevelopment environment called IDLE.If you would like to expand the programming language, it is
21、easy toextend into other modules like C or C+.Python programming can be run on any unit including Unix, Linux,Windows, and Mac OS X.The software is free. You wont have to pay anything to download anduse Python in your own life. you can also make modifications andredistribute this product. It is unde

24、ts, strings, and numbers. The Origins of Python The beginning of the modern Python programming started in December of1989. The creator of this program was Guido van Rossum who beganprogramming as more of a hobby. At the time, van Rossum was working on aproject with the Dutch CWI research institute,
25、that was later terminated. VanRossum was able to use some of the basics of this new language, known as theABC language, in order to work on Python. The main strength of this language is that it is really easy to extend upon tomake more complex, or keep simple, and it was able to support multipleplat
26、forms. Both of these were important during the days when personalcomputers were becoming popular. And since Python was designed tocommunicate with different file formats and libraries, it became a hit as well. Python has grown quite a bit since its inception and more tools have beenadded to make the
27、 programing more functioning. In addition to making Python欢迎加入非盈利Py t h o n 编程学习交流QQ群783462347，群里免费提供500+本Py t h o n 书籍！easy to use, van Rossum has been working on initiatives that encourage theeducation of coding to everyone, not just a select few. Using Python to usecoding can make things easier a
28、nd helps to get rid of some of the fearsassociated with the complex computer codes since it doesnt look so scary. Over the years, van Rossum decided to make Python open sourced. Thisallowed all to gain access and make changes to Python so that if somethinghappened to van Rossum, all would not be los
29、t. Thanks to having Python opensourced, Python 2.0 was released during 2000 to make it more communityoriented and to have a transparent development process. There are a few newerversions of Python 2.0 still being used, but Python 3 has been taking the worldby storm and most anticipate this will be t
30、he normal one used within the nextfew years. Python 3 This version of Python was released in 2008. It is not simply an update to theprogram, but a complete change in it. While there are a lot of great features thatcome with this version, it doesnt have a backward compatibility so you willhave to mak
31、e a choice between Python 2.0 and Python 3. To make thingseasier, the programmers did make a little marker within the program that wouldshow a coder what needed to be changed between the two programs when欢迎加入非盈利Py t h o n 编程学习交流QQ群783462347，群里免费提供500+本Py t h o n 书籍！uploading. Despite this, most have
32、 stuck with Python 2.0 for now. Why Use Python? As you can probably guess, there are several different computer codingprograms that you can choose to use. But while there are some benefits tousing these other programs, Python is one of the best options out there. It iseasy to use, has a lot of optio
33、ns for you to choose from, and it can even beused over a variety of platforms without having to change things up. Some ofthe benefits that you will love with Python include: Readability Python is designed to work with the English language, making it easy to read.There are also strict rules in terms
34、of punctuation on the program so you arentjust looking at brackets all over the place. Python also makes sure that theprogrammer knows how to format everything thanks to a set of rules that are inplace, making it easy for everyone to create a code that others can follow. Libraries 欢迎加入非盈利Py t h o n

Some of the benefitsthat you will get when you get started wi
44、th Python include: Easy to use and read When it comes to programming language, there are none that are as easy to useas Python. Other languages are kind of clunky and hard to look at. You maytake a look at them and notice that they have tons of brackets and even wordsthat you wont even recognize. It
45、 is enough to scare away someone who isntused to programming at all just because all the words look a bit intimidating. Python is a bit different. Instead of all the crazy brackets, it makes use ofindentations, causing an easier to read page that isnt such a mess. Instead ofwords that you cant under
46、stand, it uses English. The other special charactersare kept to a minimum so that you can look at the page of code and not feellike you are going to be overwhelmed in the process. This is one of the easiest programming tools that you can use. It looks nice onthe page and will use plenty of white spa
