Can anyone please help me in understanding the following python code

[bhk755 at gmail.com]

Thanks for the reply Chris.

I am newbie to python, so please excuse me if I am asking chilly questions.

Can you please explain more about the following sentence.
"When it says "Splitting" with a single-element list, it then 
immediately prints "Merging" and returns (because all the rest of the 
code is guarded by the 'if'). Execution then continues where it left 
off, in the parent."

Because I am not sure how the control can go back to top of the function unless  there is no loops there.

Also, Can you please let me know how did you found out that I am using Python 2 Interpreter.
