12,432 PointsIn 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?

and pop
work differently.
-
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!
