### Nie martw się stylem

* Nie przejmuj się zbytnio rzeczami takimi jak style wiadomości commitów, przy wcielaniu pull requesta łączę commity i modyfikuję opis sumarycznego commita ręcznie.

* Nie przejmuj się również stylem kodu, automatyczne narzędzia w repozytorium sprawdzają to samodzielnie.

As Python advances, **newer versions** come with improved support for these type annotations and in many cases you won't even need to import and use the `typing` module to declare the type annotations.

If you can choose a more recent version of Python for your project, you will be able to take advantage of that extra simplicity.

In all the docs there are examples compatible with each version of Python (when there's a difference).

// never the receiver, and has the effect of shutting down the channel after
// the last sent value is received. After the last value has been received
// from a closed channel c, any receive from c will succeed without
// blocking, returning the zero value for the channel element. The form
//
//	x, ok := <-c
//
// will also set ok to false for a closed and empty channel.
func close(c chan<- Type)

	if string(s) == goVersion {
		return nil
	}

	goroot, err := findGoroot()
	if err != nil {
		return err
	}

	// Delete the device's GOROOT, GOPATH and any leftover test data,
	// and recreate GOROOT.
	if err := adb("exec-out", "rm", "-rf", deviceRoot); err != nil {
		return err
	}

	// Build Go for Android.
	cmd = exec.Command(goTool, "install", "cmd")
	out, err = cmd.CombinedOutput()

In this example we are using the OAuth2 "password" flow.

This is appropriate when we are logging in to our own application, probably with our own frontend.

Because we can trust it to receive the `username` and `password`, as we control it.

    * Revisar si tiene un atributo requerido `price` que debe ser un `float`.
    * Revisar si tiene un atributo opcional `is_offer`, que debe ser un `bool`si está presente.
    * Todo esto funcionaría para objetos JSON profundamente anidados.
* Convertir de y a JSON automáticamente.
* Documentar todo con OpenAPI que puede ser usado por:
    * Sistemas de documentación interactiva.

reinstated, you do not qualify to receive new licenses for the same
material under section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,

    * verifica che la richiesta abbia un attributo obbligatorio `price` e che sia di tipo `float`.
    * verifica che la richiesta abbia un attributo opzionale `is_offer` e che sia di tipo `bool`, se presente.
    * Tutto questo funzionerebbe anche con oggetti JSON più complessi.
* Convertirà *da* e *a* JSON automaticamente.
* Documenterà tutto con OpenAPI, che può essere usato per:
    * Sistemi di documentazione interattivi.
