Learning about Bases of Python Programming Language for Newbie

Hi Brother and Sister ?
I’m sorry that I don’t have written again after long time ago, because of many activities in campus so that I rarely write some writing. OK at my writing today, I will share material about Python Programming Language. Actually the logic of each programming language is almost exact, only the process of writing is different. Maybe each programming language has each characteristic itself. But their point almost same, the most important that I have to suggest to you is how we use our logic to solve problems.

Before we learn about Python programming language, we need to have the application or compiler of Python. Do you have it my friends?
If you don’t have it, please download HERE.

Need to know that there are many versions of Python application, they are version 2.5, version 2.7, version 3.1, version 3.3 and so on. There is some differ between Python with version less than 3 and Python with version more than 3. Just be enjoy my friends, the different is not much. Don’t be worry to learn Python programming language, it is not difficult if we are serious to learn. I will describe some different between them later. The important thing is we learn about that continuely, it certain becomes fun. :)

Oh ya, has the software be downloaded and installed on your computer? If it has, let’s open the software and open IDLE. It will appear like picture below :

This is picture of Python Shell or Python Interactive Mode itself. Before writing some scripts, you have to know some types of values. There are 3 types :

1. String (str)
2. Integer (int)
3. Float (float)

I will give little description about them :

1. String is an object which formed of words or sentences. For examples, ‘World’, ’Good morning’, ’Have nice dream’, and ect.
2. Integer is an object which formed of integer numerical. For examples, number of 239, number of 12, number of 35, and ect.
3. Float is an object which formed decimal numerical. For examples number of 2.55, number of 3.11, number of 4.566, and ect.

OK friends, we continue to next step. After understanding the type of the objects, we will learn about how to print whatever we have written in the program. So, function that you should use is print function. How to use the function ? Let’s try to write something to IDLE that you open before. As I said before that Python with version 3 down and version 3 up is different. The diverification placed on writing object after print . For instance when you use Python version 3.3, object that you write after print must in brackets. See the examples below :

Then, when you use Python version 2.7 , so you don’t need to use brackets. See the examples below :

Now, you have known the different between Python version 3 down and Python version 3 up. Try to proof type of objects that you have written, for example let’s write some objects on Python Shell like this :a = “You look so beautiful”
b = 40
c = 20.7a, b, and c are variables, then check the type of the three objects by using type(variable)
See the picture below :

You have seen what the result is. if Python prints <type ‘str’> ,it means the type of the variable is String. If Python prints <type ‘int’> ,it means the type of the variable is Integer. And if Python prints <type ‘float’> it means the type of the variable is Float.I think enough for my writing today, and I will continue to next material about Learning about Input value using Python easily on next day. I hope it’s useful for you all my friends especially for newbie. That’s all from me and please wait for my next writing. Thanks ;)
