# Note that there is more than one correct answer for all of these!

# Question 1 - In one line of code, set a variable called wookie_name to the name of the wookie character

[_, _, %{name: wookie_name, type: :wookie}, _, _, _] = characters

# Question 2 - In one line of code, set a variable called 'weight' to how much Han weighs

[%{weight: weight} | _t] = characters

##### Advanced (we haven't covered all of this yet, you'll likely need to read documentation)

# Question 3 - In one line of code, create a list of the names of the humans

for %{type: :human, name: name} <- characters, do: name

# Question 4 - In one line of code, create a list of all the humans that weigh less than 180 lbs.

for c = %{type: :human} <- characters, c.weight < 180, into: [], do: c
