Я пытаюсь сравнить список дат с текущей датой и временем.
Я беру эту строку (просто быстрый пример) из удаленной команды S SH:
Mon Jun 15 16:52:18 2020,Mon Jun 15 16:52:35 2020,Mon Jun 15 16:52:29 2020 ...
Дата и время сейчас:
now = datetime.now()
Затем я конвертирую исходный формат сейчас в тот же, что и моя строка :
nowform = now.strftime("%a %b %d %H:%M:%S %Y")
Результат - именно то, что мне нужно:
Wed Jun 17 13:26:39 2020
Но теперь возникла проблема, я попытался изменить формат элементов моего списка на элементы datetime , как вы можете видеть здесь:
dates_1 = str(re.findall('(Mon.*|Sun.*|Tue.*|Wed.*|Thu.*|Fri.*|Sat.*|Sun.*)', output)).replace("\\r", "").replace(" '", "'").replace("'", "").replace("[", "").replace("]", "")#.replace(",", ";").replace(" ; ", ";")
print(dates_1)
dateslist = dates_1.split(",")
dates_list = [dt.datetime.strptime(date, "%a %b %d %H:%M:%S %Y").date() for date in dateslist]
print (dates_list)
И затем я пытаюсь взять разницу (по дням):
delta = nowform - dates_list
print(delta.days)
Результат date_list - это
[datetime.date(2020, 6, 15), datetime.date(2020, 6, 15), datetime.date(2020, 6, 15), datetime.date(2020, 6, 15), datetime.date(2020, 6, 15), datetime.date(2020, 6, 15), datetime.date(2020, 6, 15),

Но он возвращает эту ошибку:
TypeError: unsupported operand type(s) for -: 'str' and 'list'
Как это возможно, что я не могу сравнить все эти значения, если я изменил формат?
