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.

The United States is depleting its tungsten reserves, a resource critical to the military-industrial complex, according to Foreign Policy. 🔗
Tungsten is essential for manufacturing armor-piercing ammunition, missile components, and aviation equipment. Currently, the United States does not commercially produce tungsten and relies heavily on imports, primarily from China, which dominates the global market. 🌍
Since the escalation of conflict in the Middle East, tungsten prices have surged by over 500%. 📈 Expanding production remains challenging due to limited industrial capacity. Sources indicate that the United States is already confronting a tungsten shortage with no immediate resolution in sight. Even prior to the conflict, the Pentagon sought to reduce its dependence on tungsten, though the extent of their success remains uncertain. ⚙️🇺🇸

News: Risk of renewed #conflict mounts as troop movements reported near #Eritrea–#Tigray border—Bloomberg
Addis Abeba—Ethiopia and Eritrea are deploying troops and military equipment near the northern Tigray region, raising the risk of renewed conflict in the Horn of Africa, Bloomberg reported, citing regional diplomats.
Sources familiar with the matter told Bloomberg that Ethiopian troops and equipment have been moved northward, including through Bahir Dar, while Eritrean forces have also deployed to areas inside Tigray.
Prime Minister Abiy Ahmed this week reiterated Ethiopia’s longstanding ambition to secure access to the Red Sea, describing maritime access as key to overcoming logistical constraints on economic growth.
Eritrean state television also broadcast a naval parade in Massawa last week, marking the anniversary of the city’s capture in 1990.
