# Task

```python theme={"system"}
class Task:
    def execute(context: ExecutionContext) -> None

    @staticmethod
    def identifier() -> tuple[str, str]
```

Base class for Tilebox workflows [tasks](/workflows/concepts/tasks). Inherit from this class to create a task.
Inheriting also automatically applies the dataclass decorator.

## Methods

```python theme={"system"}
def Task.execute(context: ExecutionContext) -> None
```

The entry point for the execution of the task.

```python theme={"system"}
@staticmethod
def Task.identifier() -> tuple[str, str]
```

Override a task identifier and specify its version. If not overridden, the identifier of a task defaults to the class name, and the version to `v0.0`.

## Task Input Parameters

```python theme={"system"}
class MyTask(Task):
    message: str
    value: int
    data: dict[str, int]
```

Optional task [input parameters](/workflows/concepts/tasks#input-parameters), defined as class attributes. Supported types
are `str`, `int`, `float`, `bool`, as well as `lists` and `dicts` thereof.

<RequestExample>
  ```python Python theme={"system"}
  from tilebox.workflows import Task, ExecutionContext

  class MyFirstTask(Task):
      def execute(self, context: ExecutionContext):
          print(f"Hello World!")

      @staticmethod
      def identifier() -> tuple[str, str]:
          return ("tilebox.workflows.MyTask", "v3.2")

  class MyFirstParameterizedTask(Task):
      name: str
      greet: bool
      data: dict[str, str]

      def execute(self, context: ExecutionContext):
          if self.greet:
              print(f"Hello {self.name}!")
  ```
