In this video, we will be discussing the installation procedure of python.
If you want to install python from the official website, you can go to python.org, Download and install the latest version.
But I would recommend you guys to install the Anacondas distribution of python. Anacondas python distribution also has a very good IDE called Jupyter notebook. Also, many data analysis and machine learning packages come pre-installed with Anacondas.
To install Anacondas distribution of python, just type Anacondas download in google and go to the official website.
Since I have windows operating system with 64 bit architecture. I will download this version.
Since I have already downloaded the file, I will cancel the download and us the downloaded file.
Run the installer as Admin so that we can install the software for all users. Also, I would recommend checking the check box to add Anacondas to the environment variable.
The installation is done, we will now verify it by writing a simple hello world program in python.
Just open the command prompt in any folder and type jupyter notebook. The IDE will open in the default browser.
In other languages such as java or c#, even to write a simple program, we need to write a class and inside that class, there should be one main method which will be the entry point of the program. In python, there is no need to write those things.
So lets simply write print("Hello World!!"). So that’s how easy it is to write code in python. Nothing fancy here. To execute this code, we can use shift + enter or run it using this run icon.
So now that we have successfully installed python and verified, we can now start learning and practicing.
