As descriptions tend to be long and cover multiple lines, you can declare the *path operation* description in the function <abbr title="a multi-line string as the first expression inside a function (not assigned to any variable) used for documentation">docstring</abbr> and **FastAPI** will read it from there.

### Use it { #use-it }

Now you can pass that `oauth2_scheme` in a dependency with `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

This dependency will provide a `str` that is assigned to the parameter `token` of the *path operation function*.

**FastAPI** will know that it can use this dependency to define a "security scheme" in the OpenAPI schema (and the automatic API docs).

	// etag variable is assigned with that value.
	var etag string

	textData := generateBytesData(objSize)
	// generate md5sum for the generated data.

   * however that is fine since the correctness is based on the atomic state in our base class. The
   * initial write to timer is never definitely visible to Fire.run since it is assigned after
   * SES.schedule is called. Therefore Fire.run has to check for null. However, it should be visible
   * if Fire.run is called by delegate.addListener since addListener is called after the assignment
