  •  Python was Developed by Guido Van Rossum and first released in 1991 . You can click on link to view  him on LinkedIn to know what he has been doing recently. 
  • To Learn Python you need to Install it in your system.
  • We will be using the Free Anaconda Distribution  to install Python.
  •  This distribution has bundled Jupyter that we will be using as the IDE .
  • To Download Python Search on Google – Anaconda or go to the below link

Download the version based on your operating system like For Windows or MacOS or Linux

Unless and until you are working on a Project that demand Python 2.7 ( one of the most famous stable version still being widely used ) , Download the Python 3+ version as all updates comes in 3+ version and eventually 2+ would be deprecated.

The Download may take a while based on your internet speed. Once the Download is completed you can start the installation as below.

We recommend adding it to PATH environment variable. Once you click on the Check Box , a Warning will be displayed . If you are really sure that you do not want to add it to PATH you can un check this else you can ignore the warning and move ahead. Adding it to PATH allows you to call conda , jupyter notebook, and python at your command line .

After this the Installation starts

This is going to take a while . Once the installation completes you will get the below screen

Now to check if the Python got correctly installed and the path got correctly set up , open the command line prompt and type python and press “enter” . The python prompt opens up and you can write a basic command like – print(‘Hi Swara’)

Now that you have installed python and the path  setup you can even install other dependencies or packages using easy_install . For this exit python by exit() and go to the command line prompt and run the below command

Now say we want to do Image Process using OpenCV so in order to Install Open CV for Python you can simply go to command line ? cmd  and type the command ? easy_install opencv_python
