    assertEquals("/a/b/c/y", simplifyPath("/a/b/c/g;x=1/../y"));

  /** http://gbiv.com/protocols/uri/rfc/rfc3986.html#relative-normal */
  public void testRfc3986Normal() {

    assertEquals("/a/b/c/g", simplifyPath("/a/b/c/g/"));

Ela será chamada pelo **FastAPI** sempre que receber uma requisição para a URL "`/ `" usando uma operação `GET`.

Neste caso, é uma função `assíncrona`.

Você também pode defini-la como uma função normal em vez de `async def`:

```Python hl_lines="7"
{!../../docs_src/first_steps/tutorial003.py!}
```

/// note | "Nota"

        assertEquals("2012-05-18T22:45:00Z", extractData.getValues("dcterms:modified")[0]);
        assertEquals("3", extractData.getValues("meta:character-count")[0]);
        assertEquals("Normal", extractData.getValues("extended-properties:Template")[0]);
        assertEquals("たいとる", extractData.getValues("dc:title")[0]);
        assertEquals("3000000000", extractData.getValues("extended-properties:TotalTime")[0]);

		return fmt.Errorf("no online drives found for set with endpoints %s", set.getEndpoints())
	}

	// However many we ask, versions must exist on ~50%
	listingQuorum := (set.setDriveCount + 1) / 2

	// How to resolve partial results.
	resolver := metadataResolutionParams{
		dirQuorum: listingQuorum, // make sure to capture all quorum ratios
		objQuorum: listingQuorum, // make sure to capture all quorum ratios
		bucket:    bucketName,
	}

### Import `HTTPException`

```Python hl_lines="1"
{!../../docs_src/handling_errors/tutorial001.py!}
```

### Raise an `HTTPException` in your code

`HTTPException` is a normal Python exception with additional data relevant for APIs.

Because it's a Python exception, you don't `return` it, you `raise` it.

                  "drawStyle": "bars",
                  "fillOpacity": 100,
                  "gradientMode": "none",
                  "showPoints": "never",
                  "stacking": {
                     "mode": "normal"
                  }
               },
               "unit": "ops"
            },
            "overrides": [
               {
                  "matcher": {
                     "id": "byName",

                  page_numbers:
                    type: array
                    items:
                      type: string
                    example: ["1", "2", "3", "4", "5"]
                  partial:
                    type: boolean
                    example: false
                  search_query:
                    type: string
                    example: "(Fess OR n2sm)"
                  requested_time:

dation~="recaptcha"]',b).each(function(){var d=a(this),e=document.createElement("DIV"),f=c.reCaptchaSiteKey||d.valAttr("recaptcha-sitekey"),g=c.reCaptchaTheme||d.valAttr("recaptcha-theme")||"light",h=c.reCaptchaSize||d.valAttr("recaptcha-size")||"normal",i=c.reCaptchaType||d.valAttr("recaptcha-type")||"image";if(!f)throw new Error("Google reCaptcha site key is required.");var j=grecaptcha.render(e,{sitekey:f,theme:g,size:h,type:i,callback:function(a){b.find('[data-validation~="recaptcha"]').trig...

It will be called by **FastAPI** whenever it receives a request to the URL "`/`" using a `GET` operation.

In this case, it is an `async` function.

---

You could also define it as a normal function instead of `async def`:

{* ../../docs_src/first_steps/tutorial003.py hl[7] *}

/// note

	MediumBlock = 128 * humanize.KiByte // Default r/w block size for medium sized objects.
	LargeBlock  = 1 * humanize.MiByte   // Default r/w block size for normal objects.
)

// aligned sync.Pool's
var (
	ODirectPoolLarge = sync.Pool{
		New: func() interface{} {
			b := disk.AlignedBlock(LargeBlock)
			return &b
		},
	}
	ODirectPoolMedium = sync.Pool{
