Get length of list

[ReaMart]

I have a list of players and I want something to happen when there are more than 2 players in the list. How would I achieve this? And how would I send the amount of players required to chat? In my favorite programming language, python, this would be something like

if len(list) > 2:
	do something
else:
	print("not enough players, need " + str(3 - len(list)) + " more players"

if size of {list::*} > 2:

    stuff

else:

    broadcast " need %3 - (size of {list::*})% more players "
