If you're worried about that, you could create your own

t.apply(lambda x: [x]) gives
a[[1, 2, 2]]

How?? When you 't' within console the entire data frame is dumped but how are
the individual elements passed into .apply()? I can't do lambda x,y: [x,y]
I recently discovered the turtle module and have been playing
around with it for the last few days. I've started writing some
functions for turtles, and would like to make them a bit more
robustly than what I currently have.
In particular, I'd like the state of the turtle to be more or
