Running Python script with Input statement

Hi I am facing problem with receiving values using input function. I have the script 3.18.1 installed, the Python in use is 2.7.16. Please advise, thanks

Tried searching “input”?

Yes, advised about installing script-runner, but the package does not install & ends up in an error which I am not able to understand

DamnedScholar suggested here trying process-palette package so that your script runs outside Atom.
