Это мой скрипт, и я хочу напечатать и вычесть 1:
for eachNumber in range(counter, 0, -1):
print(eachNumber)
из counter для каждого цикла, который это делает. Когда я пытаюсь поместить его в цикл for, в настоящее время он печатает все полные числа, пока не достигнет counter. Я хочу, чтобы он отсчитывал от counter для каждого for video_id in ids: в сценарии.
