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.

#Breaking: Six American and British terrorist airstrikes targeted several areas in the north and south of #Yemen's capital, #Sanaa.
Do NOT ask why you are hated across the world when YOUR tax money is dropped from #B2Spirit bombers on people's heads in #Yemen
What do they tell you when you ask them "WHY ARE YOU BOMBING PEOPLE HALF WAY ACROSS THE WORLD?"
I bet your leaders tell you they are "barbaric terrorists" exactly when you are playing on your smart phone the video of the burning tents in #Gaza at the hands of THE MOST BARBARIC terrorists to have ever roamed this earth..your Zionist Friends.
Yemeni Media reported that approximately 40 U.S. airstrikes targeting the capital, #Sanaa, as well as Saada and Al-Bayda, have resulted in an initial toll of 32 dead and over 100 wounded, the majority of whom are women and children. The strikes are expected to continue for weeks.
Four airstrikes hit the Al-Jeraf neighborhood in northern Sanaa, killing ten people and injuring 13 others. Additional strikes targeted the Attan and Jarban areas in the Sanhan district of Sanaa province.
In #Saada, reports indicate that airstrikes on two homes in the Qahza area, north of the city, led to a rising casualty count of ten dead and 13 wounded.
Meanwhile, the U.S. Central Command (#CENTCOM) confirmed that it had carried out a series of airstrikes against "Ansarullah" targets across #Yemen. CENTCOM stated that the operations involved precision strikes, justifying them as measures to defend U.S. interests, deter adversaries, and restore freedom of maritime navigation.
