### Simplemente Python moderno

Todo está basado en las declaraciones de tipo de **Python 3.8** estándar (gracias a Pydantic). No necesitas aprender una sintaxis nueva, solo Python moderno.

Si necesitas un repaso de 2 minutos de cómo usar los tipos de Python (así no uses FastAPI) prueba el tutorial corto: [Python Types](python-types.md){.internal-link target=_blank}.

Escribes Python estándar con tipos así:

```Python
from datetime import date

import java.time.ZoneOffset
import java.time.format.DateTimeFormatterBuilder
import java.time.temporal.ChronoField.HOUR_OF_DAY
import java.time.temporal.ChronoField.MINUTE_OF_HOUR
import java.time.temporal.ChronoField.NANO_OF_SECOND
import java.time.temporal.ChronoField.SECOND_OF_MINUTE
import java.util.logging.Formatter
import java.util.logging.LogRecord

/**

  //   3. Signer whose configured minimum is longer than the requested duration
  //
  // The minimum valid value for expirationSeconds is 600, i.e. 10 minutes.
  //
  // +optional
  optional int32 expirationSeconds = 8;

  // usages specifies a set of key usages requested in the issued certificate.

## Automatische Konvertierung

`Header` hat weitere Funktionalität, zusätzlich zu der, die `Path`, `Query` und `Cookie` bereitstellen.

Die meisten Standard-Header benutzen als Trennzeichen einen Bindestrich, auch bekannt als das „Minus-Symbol“ (`-`).

Aber eine Variable wie `user-agent` ist in Python nicht gültig.

Darum wird `Header` standardmäßig in Parameternamen den Unterstrich (`_`) zu einem Bindestrich (`-`) konvertieren.

      require(hour in 0..23)
      require(minute in 0..59)
      require(second in 0..59)

      GregorianCalendar(UTC).apply {
        isLenient = false
        set(Calendar.YEAR, year)
        set(Calendar.MONTH, month - 1)
        set(Calendar.DAY_OF_MONTH, dayOfMonth)
        set(Calendar.HOUR_OF_DAY, hour)
        set(Calendar.MINUTE, minute)
        set(Calendar.SECOND, second)

  // to the endpoint that served this list to retrieve the next set of available objects. Continuing a
  // consistent list may not be possible if the server configuration has changed or more than a few
  // minutes have passed. The resourceVersion field returned when using this continue value will be
  // identical to the value in the first response, unless you have received this token from an error
  // message.

  //   3. Signer whose configured minimum is longer than the requested duration
  //
  // The minimum valid value for expirationSeconds is 600, i.e. 10 minutes.
  //
  // +optional
  optional int32 expirationSeconds = 8;

  // allowedUsages specifies a set of usage contexts the key will be
  // valid for.
