Why the version of python is 2.7 in Editorial and solution for this

[namnium1125]

Thank you for look.

I'm Japanese. So I might write some wrong English. then, please excuse me.

>>> a = 1
>>> b = 2
>>> 
>>> print(a,b)

When I run this code, I thought I would get the result like this:

1 2

but in fact, I got this result:

(1, 2)

then, I thought I got it simply because the version of python is 2.7 and print statement output tuple (1, 2).

And I tryed this code:

import sys

print(sys.version)

its result:

2.7.12 (default, Nov 20 2016, 12:12:11) 
[GCC 4.2.1 Compatible Apple LLVM 7.3.0 (clang-703.0.31)]

My thought was correct. but...

The version in Pythonista3 is 3, but Why in the world is the version of python in Editorial 2.7?!

And I want use Python 3.x in Editorial.

If you know somethings about this, could you tell me?

Thank you.
