Python tiene soporte para "anotaciones de tipos" opcionales (también llamadas "type hints").

Estas **"anotaciones de tipos"** o type hints son una sintaxis especial que permite declarar el <abbr title="por ejemplo: str, int, float, bool">tipo</abbr> de una variable.

Al declarar tipos para tus variables, los editores y herramientas te pueden proporcionar un mejor soporte.

پایتون از "نوع‌نما"های اختیاری (که بهشون "type hints" یا "type annotations" هم می‌گن) پشتیبانی می‌کنه.

این **"نوع‌نماها"** یا annotationها یه سینتکس خاص هستن که بهت اجازه می‌دن <abbr title="مثلاً: str, int, float, bool">نوع</abbr> یه متغیر رو مشخص کنی.

با مشخص کردن نوع متغیرها، ویرایشگرها و ابزارها می‌تونن پشتیبانی بهتری بهت بدن.

	SubSys          string         `json:"subSys"`
	Description     string         `json:"description"`
	MultipleTargets bool           `json:"multipleTargets"`
	KeysHelp        config.HelpKVS `json:"keysHelp"`
}

// GetHelp - returns help for sub-sys, a key for a sub-system or all the help.
func GetHelp(subSys, key string, envOnly bool) (Help, error) {
	if len(subSys) == 0 {
		return Help{KeysHelp: config.HelpSubSysMap[subSys]}, nil
	}

Os parâmetros da função serão reconhecidos conforme abaixo:

* Se o parâmetro também é declarado na **rota**, será utilizado como um parâmetro de rota.
* Se o parâmetro é de um **tipo único** (como `int`, `float`, `str`, `bool`, etc) será interpretado como um parâmetro de **consulta**.
* Se o parâmetro é declarado como um **modelo Pydantic**, será interpretado como o **corpo** da requisição.
