Run Python in Sublime Text 3 | using sublime package

Since Sublime Text's Default build option dose not take input, I am going to be using 2 packages from package manager In sublime text 3.
first one is terminality (good for console applications)
second one is sublimerepl (rood for data visualization projects)

I have seen hundreds of videos but nothing worked
but only yours worked

[nagarajupinnu]

THANKS YOU SO MUCH BROTHER I GONE THROUGH NUMBER OF VIDEOS NONE OF THOSE R WORKED. BUT YOUR WORKED A LOT FOR ME....

So we can put user input in the terminal right

[rachitadashore]

I followed the steps but at last it showed
"python is not recognized as an internal or external command,
Operable program or batch file"
What to do now?

[DC-sevr]
