Try to find the good side. In general, if people are not being unfriendly, try to thank their effort and interest, even if you disagree with the main subject (discussion, PR), just thank them for being interested in the project, or for having dedicated some time to try to do something.

It's difficult to convey emotion in text, use emojis to help. 😅

## Set types

But then we think about it, and realize that tags shouldn't repeat, they would probably be unique strings.

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8:9] *}

That's it.

**2 lines**.

And it has the same shape and structure that all your *path operation functions* have.

You can think of it as a *path operation function* without the "decorator" (without the `@app.get("/some-path")`).

And it can return anything you want.

In this case, this dependency expects:

	m := podsRepaired.With(typeLabel.Value(deleteType))
	repairLog.Infof("Pod detected as broken, deleting: %s/%s", pod.Namespace, pod.Name)

	// Make sure we are deleting what we think we are...
	preconditions := &metav1.Preconditions{
		UID:             &pod.UID,
		ResourceVersion: &pod.ResourceVersion,
	}

In previous versions of NodeJS / Browser JavaScript, you would have used "callbacks". Which leads to <a href="http://callbackhell.com/" class="external-link" target="_blank">callback hell</a>.
