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!}
```
