Using multiple lists in a function is no different from just using multiple arguments in a function!

a = [1, 2, 3] b = [4, 5, 6] print a + b # prints [1, 2, 3, 4, 5, 6]

The example above is just a reminder of how to concatenate two lists.



Create a function that joins two lists together.

  • On line 5, define a function called join_lists that has two arguments, x and y. They will both be lists.
  • Inside that function, return the result of concatenating x and y together.
