### Classes como tipos

Você também pode declarar uma classe como o tipo de uma variável.

Digamos que você tenha uma classe `Person`, com um nome:

```Python hl_lines="1 2 3"
{!../../../docs_src/python_types/tutorial010.py!}
```

Então você pode declarar que uma variável é do tipo `Person`:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

		{call: "Setgroups([]int{0,1,2,3})", fn: func() error { return syscall.Setgroups([]int{0, 1, 2, 3}) }, filter: "Groups:", expect: "\t0 1 2 3"},
		{call: "Setgroups(nil)", fn: func() error { return syscall.Setgroups(nil) }, filter: "Groups:", expect: ""},

	AssertEqual(t, true, ok)

	//  empty string -> 123
	err = DB.Table("unique_tests").AutoMigrate(&UniqueTest4{})
	if err != nil {
		t.Fatalf("AutoMigrate err:%v", err)
	}

	ct, err = findColumnType(&UniqueTest{}, "name")
	if err != nil {
		t.Fatalf("findColumnType err:%v", err)
	}

	value, ok = ct.DefaultValue()
	AssertEqual(t, "123", value)
	AssertEqual(t, true, ok)

	//  123 -> null
