您能在Python中创建变量列表而不实例化变量吗？

Question

我想让我的代码更干净。你知道吗

我想做一些类似的事情：

gesture_sensor_data = [nod_gyro, nod_acc, swipe_left_gyro, swipe_right_acc, etc.]

我现在有这个：

nod_gyro, nod_acc = fill_gyro_and_acc_data(nod_intervals, merge)
swipe_right_gyro, swipe_right_acc = fill_gyro_and_acc_data(swipe_right_intervals, merge)
swipe_left_gyro, swipe_left_acc = fill_gyro_and_acc_data(swipe_left_intervals, merge)
whats_up_gyro, whats_up_acc = fill_gyro_and_acc_data(whats_up_intervals, merge)

我想通过gesture_sensor_data运行一个循环。你知道吗

有办法吗？某种结构什么的？你知道吗

编辑：我将在这个函数中显示我的完整代码作为上下文。你知道吗

def generate_gesture_files(i):
    nod_intervals, swipe_left_intervals, swipe_right_intervals, whats_up_intervals = generate_gesture_intervals(i)

    merge = pandas.read_csv(final_user_study_path + "/P" + str(i) + "/DataCollection/data/merge.csv")
    nod_gyro, nod_acc = fill_gyro_and_acc_data(nod_intervals, merge)
    swipe_right_gyro, swipe_right_acc = fill_gyro_and_acc_data(swipe_right_intervals, merge)
    swipe_left_gyro, swipe_left_acc = fill_gyro_and_acc_data(swipe_left_intervals, merge)
    whats_up_gyro, whats_up_acc = fill_gyro_and_acc_data(whats_up_intervals, merge)
    return nod_gyro, nod_acc, swipe_right_gyro, swipe_right_acc, swipe_left_gyro, swipe_right_acc, whats_up_gyro, whats_up_acc

Answer 1

您可以更改生成\u手势\u间隔并使用部分

def generate_gesture_files(i):
  return reduce(lambda x,y:x+y, [fill_gyro_and_acc_data(arg, merge) for arg in generate_gesture_intervals(i)])

Answer 2

itertools.chain([fill_gyro_and_acc_data(i, merge) for i in [
    nod_intervals, swipe_right_intervals, swipe_left_intervals, whats_up_intervals
])
