Hello , welcome to Mohammed’s Python
Tutorial series. The reason I chose Python programming language to do this tutorial is because Python is a
very easy language to learn. If you are new to programming , you just came to
the right place place. In this first tutorial, I’ll be going on how to do the
basic and simple “Hello World “ Program. If you have a Python 3 or a newer
version of Python installed ,then lets start along. First open the Python IDLE (and by the way IDLE
stands for Interactive Development Environment) .
It will look like this.
Interactive shell /IDE/
|
And then click on the File
>> New window to start a new project (Or just press Ctrl +
N).This will open a new black space to do the actual coding.You can type in the
code in the Python shell but this will be more organized and will help you
understand the code better.

Blank
Project

And then type in the following piece of
code.
Source
code
|
Small and simple as you can see. When you
run this you will be asked to save it.
You will give it a name. I named mine ‘hello world’. Any python file is saved with a .py or .pyw extension.You just type in the name and python will add .py for you.
And when you run this >>
Output
|
Yaay, you just made a very simple program
that outputs Hello World! Yeah , what a start , everything is working perfect!
The only code we wrote is –
#My first program
print("Hello
World!!")
Now
lets go through the code. The first line is a comment. It have no effect on the
program. It is useful when you write long lines of code to kind of document
what you are coding. Anything written next to a hashtag (#) will be treated as
a comment. But the next line is a piece of code which will print Hello World.
The print() function will print whatever
you write in the parameters. You just have to make sure you write the string of
text in a parentheses (“ ”).
So that was all for today ,, it will be a
long and fun journey. We will learn how to do some very awesome programs in
Python. You can keep up with me in this
blog or if you get this in somewhere else my blog is @ www.mamesblog7.blogspot.com , don’t forget to leave a comment
and put it on your RSS Feed because I’ll be posting more and more Python
tutorials.
Goodbye
