Fastapi run a background task easily

**tutorial: running a background task in fastapi**

in fastapi, you can easily run background tasks by utilizing the `backgroundtasks` dependency that is provided by the framework. background tasks are useful for handling long-running processes asynchronously without blocking the main request-response cycle.

**step 1: import the necessary modules**
make sure you have fastapi installed. you can install it using pip:

**step 2: create a fastapi app instance**

**step 3: define a background task function**
create a function that represents the background task you want to run. this function should take `backgroundtasks` as a parameter, which allows you to add tasks to be executed in the background.

**step 4: create an endpoint to trigger the background task**
define a fastapi endpoint that will trigger the background task when accessed.

**step 5: run the fastapi application**

**step 6: test the endpoint**
you can now test the `/trigger-background-task` endpoint using a tool like `curl` or postman. when you access this endpoint, a background task will be added and executed asynchronously.

example of running the fastapi application:

example of triggering the background task using `curl`:

by following these steps, you can easily run background tasks in fastapi to handle long-running processes asynchronously. this can be useful for tasks such as sending emails, processing data, or any other operation that should not block the main request-response cycle.
