您可以在Python中创建变量列表而无需实例化变量吗？

Question

我正在努力使我的代码更清洁。

我想做的事情如下：

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。

有没有办法做到这一点？ 某种结构还是什么？

编辑：我将在此函数中显示我的完整代码以供上下文使用。

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

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

Answer 2

你可以改变你的generate_gesture_intervals并使用partial

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)])
