How about:

import random

l = ["A","D","$","5","R"]
randomList = [l[random.randrange(0, len(l))] for i in range(random.randrange(1,
len(l) + 1))]

This assumes you want at least one item in the list.  Also, please note that
using "list" as a variable name is bad as it is the name of a built-in type.
