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.

News: Overloaded Isuzu truck carrying dozens atop grain overturns, leaving at least 19 dead in #Amhara region
The accident shows the persistent risks associated with the widespread use of cargo trucks for passenger transport in rural Ethiopia, where limited transport options, now exacerbated by chronic fuel shortages across the country, often force residents to travel under dangerous conditions.
Many of the victims were residents of the same locality, often traveling together in groups for work between Tsagibji and Ebnat localities. “Yesterday [Sunday] alone, we sent 17 bodies back to one specific area,” the official said, adding that several victims were members of the same families.
The Deputy Commander also said the area where the accident occurred has been under the control of Fano fighters for the past three years, preventing authorities from reaching the scene to investigate the cause of the crash.

#Ethiopia: Federal Police say its forces "seize illegal weapons" intended for "terrorist purposes" after arriving in #Addis_Abeba from #Amhara region
Addis Abeba: The Ethiopian Federal Police claimed its forces have “seized illegal weapons”, “intended for terrorist purposes” after the arms allegedly arrived in Addis Abeba “from the Amhara region.”
In a statement, the Federal Police said the first seizure occurred at the Legetafo checkpoint, where officers “intercepted a vehicle”.
Following what the federal police claimed as a “rigorous inspection,” authorities discovered “eight AK-47 assault rifles, 151 rounds of AK-47 ammunition, 17 rounds of Bren machine gun ammunition, and seven AK-47 magazines concealed inside the vehicle.”
“The illegal weapons were being transported for terrorist purposes,” the Federal Police said, adding that the suspects were “detained at the scene.”
