Can you create a list of variables in Python without instantiating the variables?
我正在努力使我的代码更清晰。
我想做如下的事情：
1 | gesture_sensor_data = [nod_gyro, nod_acc, swipe_left_gyro, swipe_right_acc, etc.] |
我现在有这个：
1 2 3 4 | 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
有办法吗？某种结构还是什么？
编辑：我将在这个函数中为上下文显示我的完整代码。
1 2 3 4 5 6 7 8 9 | 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 |
1 2 3 | itertools.chain([fill_gyro_and_acc_data(i, merge) for i in [ nod_intervals, swipe_right_intervals, swipe_left_intervals, whats_up_intervals ]) |
您可以更改生成手势的时间间隔并使用部分
1 2 | 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)]) |
