如果你需要2分钟来学习如何使用 Python 类型（即使你不使用 FastAPI），看看这个简短的教程：[Python 类型](python-types.md)。

编写带有类型标注的标准 Python：

```Python
from datetime import date

from pydantic import BaseModel

# 将变量声明为 str
# 并在函数内获得编辑器支持
def main(user_id: str):
    return user_id


# 一个 Pydantic 模型
class User(BaseModel):
    id: int
    name: str
    joined: date
```

可以像这样来使用：

```Python

package lex

import (
	"fmt"
	"os"
	"path/filepath"
	"slices"
	"strconv"
	"strings"
	"text/scanner"

	"cmd/asm/internal/flags"
	"cmd/internal/objabi"
	"cmd/internal/src"
)

// Input is the main input: a stack of readers and some macro definitions.
// It also handles #include processing (by pushing onto the input stack)
// and parses and instantiates macro definitions.
type Input struct {
	Stack

```bash
# Imprimir uma saudação ao universo
echo "Hello universe"
```

...e um exemplo de código de console...

```console
$ <font color="#4E9A06">fastapi</font> run <u style="text-decoration-style:solid">main.py</u>
<span style="background-color:#009485"><font color="#D3D7CF"> FastAPI </font></span>  Starting server
        Searching for package file structure
```

...e outro exemplo de código de console...

```console

        this.classWorld = classWorld;
        this.messageBuilderFactory = new JLineMessageBuilderFactory();
    }

    public static void main(String[] args) {
        int result = main(args, null);

        System.exit(result);
    }

    public static int main(String[] args, ClassWorld classWorld) {
        MavenCli cli = new MavenCli();

        MessageUtils.systemInstall();

 * <p><b>For users targeting Android API level 24 or higher:</b> This class will eventually
 * implement {@code BiPredicate<T, T>} (as it does in the main Guava artifact), but we currently
 * target a lower API level. In the meantime, if you have support for method references you can use
 * an equivalence as a bi-predicate like this: {@code myEquivalence::equivalent}.
