#### List

For example, let's define a variable to be a `list` of `str`.

//// tab | Python 3.9+

Declare the variable, with the same colon (`:`) syntax.

As the type, put `list`.

As the list is a type that contains some internal types, you put them in square brackets:

```Python hl_lines="1"
{!> ../../docs_src/python_types/tutorial006_py39.py!}
```

////

//// tab | Python 3.8+

      }

      @Override
      public boolean tryAdvance(Consumer<? super R> action) {
        if (fromSpliterator.tryAdvance(this)) {
          try {
            // The cast is safe because tryAdvance puts a T into `holder`.
            action.accept(function.apply(uncheckedCastNullableTToT(holder), index++));
            return true;
          } finally {
            holder = null;
          }
        }

      }

      @Override
      public boolean tryAdvance(Consumer<? super R> action) {
        if (fromSpliterator.tryAdvance(this)) {
          try {
            // The cast is safe because tryAdvance puts a T into `holder`.
            action.accept(function.apply(uncheckedCastNullableTToT(holder), index++));
            return true;
          } finally {
            holder = null;
          }
        }

Était-ce `upper` ? `uppercase` ? `first_uppercase` ? `capitalize` ?

Vous essayez donc d'utiliser le vieil ami du programmeur, l'auto-complétion de l'éditeur.

Vous écrivez le premier paramètre, `first_name`, puis un point (`.`) et appuyez sur `Ctrl+Espace` pour déclencher l'auto-complétion.

Mais malheureusement, rien d'utile n'en résulte :
