Why my code won't work as matrix

Question

I write this code on my gnu/linux with python 2.7.

Is this a problem of app or is this a problem of python version?

Answer 2

I've only used this version so can't tell you that. I'm running the same version on my laptop.

Answer 3

SoloLearn's Python requires () on prints and ,end="" to stop newlines after outputing so:
print (On, end="")
else:
print (Off, end="")
print ()
