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 island nation of Kiribati is so spread out that it once straddled the International Date Line. In 1995, it shifted the line eastward, so the entire country could share the same date. ✨

🌍 Time zones are not always set by longitude—some countries, like China, use one time zone nationwide despite spanning five natural zones, affecting daily life from sunrise to sunset across vast distances. ✨

🌍 Some time zones offset by just 15 or 30 minutes exist, like India’s UTC+5:30 and Newfoundland’s UTC−3:30. These unusual divisions reflect local choices instead of sticking to whole hours. ✨

🌍 China spans five time zones but uses only one national time, called China Standard Time. This means sunrise can happen as late as 10 a.m. in some far western regions. ✨

Kiribati starts the New Year exactly now!!!
At midnight (UTC+14). When it’s midnight there, it’s still 10 AM in London, 11 AM in Brussels (Europe, Belgium), and 1 PM in Moscow on December 31. Europe welcomes the New Year 12–14 hours after Kiribati. ⏰🌏🎉

🌍 Some Antarctic research stations use New Zealand’s time zone, while others choose the time of their home country. This means clocks at the South Pole can show different times—sometimes up to 12 hours apart. ✨
