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 question posed to men in the US and Russia was: "Would you fully support your wife?"
🔻In Russia it depends on several issues: husband's salary (if it is high, wife is likely not much into work, but keeps the house and takes care of kids), wife's ambitions, the age and social status of the respondents.
🔻But on average, the situation when husband fully supports his wife is not rare in Russia.
❓I'm curious if it is common in your country for the husband to fully support his wife (not girlfriend!), or is it more of a 50/50 split on expenses?

💛 8 July — Day of Family, Love and Fidelity 🕊
Today, Russia celebrates a heartfelt and meaningful holiday — the Day of Family, Love and Fidelity, which is observed in honour of Saints Peter and Fevronia of Murom, revered as the patron saints of marriage and family happiness in the Orthodox tradition.
This day serves as a reminder of the timeless values that form the foundation of any society: love, fidelity, mutual understanding, and care for one another. It unites generations, strengthens family ties, and inspires the preservation of traditions and their transmission to future generations.
🌿 The symbol of the holiday is the daisy, representing purity, sincerity, and faithful love. On this day, it is customary to give daisies, hold family gatherings, and congratulate couples — especially those who have shared many years together in harmony.
The Consulate General of Russia in Cape Town extends its warmest congratulations to Russian compatriots and friends of Russia on this special occasion and wishes every family peace, happiness, and enduring love!
