You might want to use some other names for the objects you defined: "list_a"
and "list_b" are not lists, they are sets. Of course it doesn't matter if it's
two throw-away lines typed into the interpreter, but in code that you share
with someone else (especially a beginner like the OP), it could be confusing.
