Python Lecture 1 - Introduction

The Python Tutorial

Python is easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms. 

Python is the most useful language for many applications like Machine Learning, web development, Desktop application development, Games and 3D graphics. In this tutorial series, we will discuss the world's most popular language python using for the most popular applications like machine learning, Data Science and artificial intelligence.

This Tutorial is for everyone who is more interested and wanted to learn the python in a best and easiest way. I will teach you each and every concept in an easy way.

What are the prerequisites: Do not worry much about the prerequisites as we are going to discuss each and every topic in a simple way. You just stay with me and keep your interest towards python the same.

Python Environment:

First of all, you need to download the python from the official python website Python_Download. If you are using a Linux machine, don't worry python will be already installed in it. If python is not installed in your systems follow the link Install_Python.

When you type the python in terminal it will open the python environment like the below code.

$ python
Python 2.4.3 (#1, Nov 11 2010, 13:34:43)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

Type the following text at the Python prompt and press the Enter on the keyboard

print("hello world!") #if the version of python is >=3
print "hello world!" #if the version is < 3

This will result in the following output:

hello world!

This is just an introduction of setting up the python environment and how it looks like. In the next tutorial, we will go into the real python from basics. So keep to the website and we'll post everyday new post and tutorial about the all the concepts of python into the advanced level and later we will go for the machine learning concepts also.

I hope you like the introduction if you really like the website subscribe using your email so that you can be notified when new post released in the blog.

Thank you, guys!!!!
