I recently downloaded anaconda software for my windows 8.1 for free, guess what it gave me?It was a triple combo pack of Jupiter notebook, python and spyder web and many other features.
In today’’s world none of us has time to deal with requirements for any software or OS download because it needs time to fulfill the requirements, so anaconda does every single work to configure python amd jupiter.
Main reasons are that it can be downloaded in any 3 of OS’’s like MAC, WINDOWS and LINUX
