### Generic types with type parameters

There are some data structures that can contain other values, like `dict`, `list`, `set` and `tuple`. And the internal values can have their own type too.

These types that have internal types are called "**generic**" types. And it's possible to declare them, even with their internal types.

#### Types génériques

Les types qui peuvent contenir des paramètres de types entre crochets, comme :

* `List`
* `Tuple`
* `Set`
* `Dict`
* `Optional`
* ...et d'autres.

sont appelés des **types génériques** ou **Generics**.

### Classes en tant que types

Vous pouvez aussi déclarer une classe comme type d'une variable.
