# Extra Data Types

Up to now, you have been using common data types, like:

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types

* `Decimal`:
    * 标准的 Python `Decimal`。
    * 在请求和响应中被当做 `float` 一样处理。
* 您可以在这里检查所有有效的pydantic数据类型: <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">Pydantic data types</a>.

## 例子

下面是一个*路径操作*的示例，其中的参数使用了上面的一些类型。

=== "Python 3.10+"

    ```Python hl_lines="1  3  12-16"
    {!> ../../../docs_src/extra_data_types/tutorial001_an_py310.py!}
    ```

	if mode&(Background|ShowOutput) == ShowOutput {
		xcmd.Stdout = os.Stdout
		xcmd.Stderr = os.Stderr
		err = xcmd.Run()
	} else {
		data, err = xcmd.CombinedOutput()
	}
	if err != nil && mode&CheckExit != 0 {
		outputLock.Lock()
		if len(data) > 0 {
			xprintf("%s\n", data)
		}
		outputLock.Unlock()
		if mode&Background != 0 {
			// Prevent fatalf from waiting on our own goroutine's
			// bghelper to exit:

		cc = append(cc, newComponent(suffix+"_data", asmKind(arch.ptrSize), "interface data", off+arch.ptrSize, arch.ptrSize, suffix))

	case asmInterface:
		cc = append(cc, newComponent(suffix+"_itable", asmKind(arch.ptrSize), "interface itable", off, arch.ptrSize, suffix))
		cc = append(cc, newComponent(suffix+"_data", asmKind(arch.ptrSize), "interface data", off+arch.ptrSize, arch.ptrSize, suffix))

	case asmSlice:

	transportConfig := config.transportConfig()
	if insecureSkipTLSVerify {
		transportConfig.TLS.Insecure = true
		transportConfig.TLS.CAFile = "" // we are only using files so we can ignore CAData
	}

	if config.Lookup != nil {
		// Assuming EgressSelector if SSHTunnel is not turned on.
		// We will not get a dialer if egress selector is disabled.
		networkContext := egressselector.Cluster.AsNetworkContext()
