+Returns `True` if two lists contain the same elements regardless of order, `False` otherwise.
+
+Use `set()` on the combination of both lists to find the unique values.
+Iterate over them with a `for` loop comparing the `count()` of each unique value in each list.
+Return `False` if the counts do not match for any element, `True` otherwise.

+```py
+def have_same_contents(a, b):

+    if a.count(v) != b.count(v):
+      return False
+  return True
+```

+```py
+have_same_contents([1, 2, 4], [2, 4, 1]) # True
