In the Dungeon Game video, why use remove and not pop?

So, why remove and not pop? I mean remove deletes a value (as I understand). So how come is doesn't delete permanently the removed value?

And why x, y = player and not player = x, y?

remove and pop work differently. :point_left:

  • remove searches for the argument provided within the list, and if it finds it, it will remove it. It returns nothing, and it only deletes the first find.
  • pop takes an index as a value, and "pops" the element at that index. It returns the element it popped. It doesn't search for the argument, as it directly takes in an index.

So I suppose in this case it is easier to use remove instead of pop.

As for player = x, y and x, y = player, they are two completely different statements. (No, they don't do the same thing.) The first statement assigns player to a tuple containing the values (x, y). The second statement "unpacks" player, and assigns each variable to the corresponding value in the tuple player. For more info on unpacking, watch this video.

I hope this clears things up! :grin:
