Я пытаюсь выполнить парсинг в Интернете с помощью Selenium, и есть вкладки, которые я открываю для получения некоторой информации, но затем хочу закрыть. Если бы я этого не делал, к тому времени, когда код завершился, у меня было бы открыто много вкладок. Я попытался переключиться на вкладку, которую хочу закрыть, а затем попытался закрыть ее, выполнив следующие действия:
browser.switch_to.window(browser.window_handles[1])
browser.close()
Когда я запускаю программу, вкладки остаются открытыми, а там, где обычно находится URL, написано «about: blank». Есть ли способ полностью закрыть эту вкладку, оставив все остальные открытыми? Ниже приведен полный код для справки.
