Untitled

decorator `atualizar` that prints the start and end time of the `tempo` function execution, which simulates an update process by sleeping for a second. The snippet also shows how to apply the decorator both directly and through a commented-out alternative method.

from datetime import datetime
from time import sleep 

def atualizar(sistema):
    def horario_de_inicio():
        print(datetime.now().strftime('%H:%M:%S'))
        sistema()
        print(datetime.now().strftime('%H:%M:%S'))
    return horario_de_inicio 

@atualizar # Primeiro modo
def tempo():
    print('Atualizando...')
    sleep(1)
tempo() # Primeiro modo


# pronto = atualizar(tempo) ## Segundo modo
# pronto() ## Segundo modo
