If you can use the **latest versions of Python**, use the examples for the latest version, those will have the **best and simplest syntax**, for example, "**Python 3.10+**".

#### List { #list }

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

//// tab | Python 3.9+

اگه بتونی از **جدیدترین نسخه‌های پایتون** استفاده کنی، از مثال‌های نسخه آخر استفاده کن، چون اونا **بهترین و ساده‌ترین سینتکس** رو دارن، مثلاً "**Python 3.10+**".

#### لیست

مثلاً، بیایم یه متغیر تعریف کنیم که یه `list` از `str` باشه.

//// tab | Python 3.9+

متغیر رو با همون سینتکس دونقطه (`:`) تعریف کن.

Here's a general idea of how the models could look like with their password fields and the places where they are used:

{* ../../docs_src/extra_models/tutorial001_py310.py hl[7,9,14,20,22,27:28,31:33,38:39] *}


/// info

In Pydantic v1 the method was called `.dict()`, it was deprecated (but still supported) in Pydantic v2, and renamed to `.model_dump()`.

* If you are in a Python version lower than 3.9, import their equivalent version from the `typing` module
* Pass the internal type(s) as "type parameters" using square brackets: `[` and `]`

In Python 3.9 it would be:

```Python
my_list: list[str]
```

In versions of Python before 3.9, it would be:

```Python
from typing import List

my_list: List[str]
```
