I assume you're talking about the while-loop (because on my machine, it 
hangs just using 'from turtle...' or 'import turtle').

That looks to be a repeat-N-times loop. There isn't a dedicated 
statement for that, the closest Python feature would be 'for i in 
range(n)' with i a dummy loop variable.
