    namespace_name: str,
    function_name: str,
    function_description: str,
    function_code: FunctionCode,
    function_runtime: str = 'Python3',
    function_type: str = None,
    function_configure: dict = None
)
```

## 返回值

该方法返回可等待操作对象，这将允许您等待无服务器云函数资源真正地创建完成。

{% content-ref url="/pages/-M4ET-juBkynutmGcsq8" %}
[Waitable 类](/tencent-cloud-sdk/python-docs/other-products/class-and-method/waitable.md)
{% endcontent-ref %}

### 兼容性

在 Tencent Cloud SDK for Python 0.1.6 或更低版本中，该方法没有返回值。

## 异常

该方法可能会主动引发以下异常：

#### ValueError

参数值或类型不符合预期。

#### ActionError

Tencent Cloud API 错误。例如访问凭据无效、给定无服务器云函数不存在等均会引发该异常。

## 示例

下面我们将通过一段 Python 代码向您演示如何使用该方法：

```python
function_client.create_function(
    region_id = 'ap-shanghai',
    namespace_name = 'default',
    function_name = 'addend',
    function_description = 'Addition function'，
    function_code = functions.FunctionCode().use_object_storage_bucket(
        region_id = 'ap-shanghai-1',
        bucket_id = 'scf-code',
        object_name = 'source.zip'
    ),
    function_runtime = functions.FunctionRuntime.Python,
    function_type = functions.FunctionType.Event,
    function_configure = {
        'handler': 'index.main',
        'memory_size': 128,
        'time_out': 3
    }
)
```
