answer:Для обработки параметров даты загрузок, которые могут быть переданы как один аргумент или два аргумента, можно использовать библиотеку argparse в Python. Вот пример кода: ```python import argparse parser = argparse.ArgumentParser() parser.add_argument('start_date', help='Дата начала загрузок в формате гггг-мм-дд') parser.add_argument('end_date', nargs='?', help='Дата окончания загрузок в формате гггг-мм-дд') args = parser.parse_args() start_date = args.start_date end_date = args.end_date if args.end_date else start_date # Далее можно использовать значения start_date и end_date в вашем скрипте ``` В данном примере `start_date` - обязательный аргумент, а `end_date` - необязательный аргумент (благодаря настройке `nargs='?'`). Если не указать `end_date`, то она будет равна `start_date`. Вы можете изменить сообщения Help для аргументов, добавить проверки на корректность введенной даты и т.д. по необходимости.

answer:Если вы хотите добавить условие, чтобы при указании параметра `--fil-empty-dates` нельзя было передать `start_date` и `end_date`, можно использовать метод `add_mutually_exclusive_group()` из модуля `argparse`. Вот пример кода: ```python import argparse parser = argparse.ArgumentParser() group = parser.add_mutually_exclusive_group() group.add_argument('--fill-empty-dates', action='store_true', help='Заполнить пустые даты') group.add_argument('--start-date', help='Дата начала загрузок в формате гггг-мм-дд') group.add_argument('--end-date', help='Дата окончания загрузок в формате гггг-мм-дд') args = parser.parse_args() fill_empty_dates = args.fill_empty_dates start_date = args.start_date end_date = args.end_date if fill_empty_dates and (start_date or end_date): parser.error("Параметр --fill-empty-dates не может быть указан с start_date или end_date") # Далее можно использовать значения fill_empty_dates, start_date и end_date в вашем скрипте ``` В данном примере параметр `--fill-empty-dates` указывается через флаг `--fill-empty-dates` и имеет тип `store_true`, что означает, что если флаг указан, то переменной `fill_empty_dates` будет присвоено значение `True`. Затем мы проверяем, если `fill_empty_dates` установлен в `True` и `start_date` или `end_date` не являются `None`, то вызываем `parser.error()` для вывода сообщения об ошибке. Вы можете изменить сообщения Help, проверки на корректность введенных дат и другие параметры по своему усмотрению.
