This snippet demonstrates a decorator 'atualizar' that tracks the execution time of a function by printing the current time before and after the function call. It showcases both its usage with the '@' syntax and as a separate call to illustrate alternative approaches.

from datetime import datetime
from time import sleep 

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