+# assert: base assert allowing you to write your own assertions
+# assertEqual(a, b): check a and b are equal
+# assertNotEqual(a, b): check a and b are not equal
+# assertIn(a, b): check that a is in the item b
+# assertNotIn(a, b): check that a is not in the item b
+# assertFalse(a): check that the value of a is False
+# assertTrue(a): check the value of a is True
+# assertIsInstance(a, TYPE): check that a is of type "TYPE"
+# assertRaises(ERROR, a, args): check that when a is called with args that it raises ERROR

+# There are more methods available to us, which you can view - see
