  """Sleep 1 second before calling the function"""
  @functools.wraps(func)
  def wrapper_slow_down(*args, **kwargs):
    #stop code to play one secend
    time.sleep(1)
    #return called functon
    return func(*args, **kwargs)

    if from_number < 1:
        print("Liftoff")
    else:
        print(from_number)
        #calling self # recursive function
        countdown(from_number - 1)
        
#calling function with 4
countdown(4)
