Right! That's how Python's assignment always works. You may find, in
your case, that you can simply reassign peca={} every time through the
loop. No copying necessary - just make yourself a new dict for each
iteration.

And you might be able to do the whole thing with a gigantic
list/list/dict comprehension, but that may or may not be an
improvement on your code :)
