Тип строки в Python имеет очень много удобных методов. Сегодня пост про два таких метода которые чаще всего используются "однобоко". Это методы startswith() и endswith() Самый обычный сценарий использования — проверка, начинается ли строка с указанной подстроки? >>> "some_string".startswith("some") True И аналогичная ситуация с зеркальным вариантом этой функции, проверка совпадения с конца >>> "some_string".endswith("some") False Так они используются в большинстве случаев что я видел. Но у этих функций есть еще два варианта использования. 🔸Сравнение нескольких подстрок Для проверки нескольких подстрок в одной строке обычно вызывают эти функции несколько раз. Но на самом деле достаточно передать кортеж со всеми строками один раз. Если будет хоть одно совпадение то функция вернёт True. >>>"my_image.png".endswith(("jpg", "png", "exr")) True 🔸Диапазон поиска Вторым аргументом можно передать индекс символа с которого следует начать сравнение, а третий аргумент это индекс последнего символа. >>> ".filename.ext".startswith("file", 1) True >>> "file_###.ext".endswith('#', 0, -4) True Индексы можно указать отрицательными, что означает отсчёт с конца. #trics#basic
