La palabra "**servidor**" se utiliza comúnmente para referirse tanto al computador remoto/en la nube (la máquina física o virtual) como al programa que se está ejecutando en esa máquina (por ejemplo, Uvicorn).

Solo ten en cuenta que cuando leas "servidor" en general, podría referirse a una de esas dos cosas.

return errOpen } counterCrypt(&g.cipher, out, ciphertext, &counter) return nil } func gcmLengths(len0, len1 uint64) [16]byte { return [16]byte{ byte(len0 >> 56), byte(len0 >> 48), byte(len0 >> 40), byte(len0 >> 32), byte(len0 >> 24), byte(len0 >> 16), byte(len0 >> 8), byte(len0), byte(len1 >> 56), byte(len1 >> 48), byte(len1 >> 40), byte(len1 >> 32), byte(len1 >> 24), byte(len1 >> 16), byte(len1 >> 8), byte(len1), } } golang.org/fips140@v1.1.0-rc1/fips140/v1.1.0-rc1/aes/gcm/gcm_ppc64x.s // Copyright 2019...

Lo mismo aplica para:

* `gt`: `g`reater `t`han
* `le`: `l`ess than or `e`qual

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

## Validaciones numéricas: flotantes, mayor y menor { #number-validations-floats-greater-than-and-less-than }

Das Gleiche gilt für:

* `gt`: `g`reater `t`han (größer als)
* `le`: `l`ess than or `e`qual (kleiner oder gleich)

{* ../../docs_src/path_params_numeric_validations/tutorial005_an_py39.py hl[10] *}

## Validierung von Zahlen: Floats, größer und kleiner { #number-validations-floats-greater-than-and-less-than }

/// note

`PATCH` is less commonly used and known than `PUT`.

And many teams use only `PUT`, even for partial updates.

You are **free** to use them however you want, **FastAPI** doesn't impose any restrictions.

But this guide shows you, more or less, how they are intended to be used.

## Execution of dependencies with `yield` { #execution-of-dependencies-with-yield }

The sequence of execution is more or less like this diagram. Time flows from top to bottom. And each column is one of the parts interacting or executing code.
