Проблема записи в файл

/ 25 мая 2018

У меня проблемы с записью в мой HTML-файл.

Я хочу, чтобы мой код мог размещать то, что я написал в HTML, но мой код будет делать это только тогда, когда у меня его нетХотя / если заявления в этом определении.Если у меня есть Whiles / Ifs, мой HTML-файл просто станет пустым.Я понятия не имею, почему это происходит, и я не могу найти обходной путь.

Есть ли способ использовать Whiles / Ifs, не заставляя мой код удалять все в моем файле, а вместо этого заставлять его писать что?Я хочу туда?

Примечание: "total_cost_list" и "list_of_items" - это все списки."total_cost" является значением.Не слишком переживайте по поводу их контекста, но я хотел уточнить, может ли это на что-нибудь повлиять.

Я вернулся к своему старому использованию цикла for и попытался использовать его.За исключением этого времени, я добавил html_formatting_mid + = ("" "к нему, а затем перед циклом for просто добавил html_formatting_mid =" ", как показал Minion Jim.

Теперь он работает полностью.

Короткий ответ будет, вы можете просто написать в режиме добавления.open (filename, 'a') вместо open (filename, 'w').Это добавит к тому, что уже есть в файле, поэтому вы можете сначала его обрезать.
