python new test frameworks

Python new test frameworks are required.

nice :)

could anyone explain what makes 2*(n-1) option better than n*2-2?

During C programming it's becoming a habit, couse without semicolon in every place where it should be your program won't run

LOL, why here all solutions are very similary)

Wow, it's really clever "D

that's what i'm asking myself every time i see other people's solutions

I'd like to see some test cases that lead to networks with longer-running iterations, though I understand that there are several factors that might make this difficult.

I had set a limit of t < 10 while developing my solution and was surprised that I passed all of the test cases without making t indefinite.

Nice ))
