Instruction

Good job! It's time to wrap things up. First, let's review our new skills. We've learned:

  1. To create a set from a list: 
    set(list_name)
  2. To eliminate duplicates from a list: 
    list(set(list_name))
  3. To combine multiple set operators: 
    set_1 & set_2 & set_3 & set_4
(set_1 | set_2) - set_3 - set_4
  4. To check if set_1 is a subset/superset of set_2 using an operator: 
    set_1 <= set_2
set_1 >= set_2
  5. Sets can be used to store all previous states of a state machine. To check if a new state already exists in the set: 
    if new_state in previous_states:
  ...
