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: #Ethiopia wheat imports to persist as rising prices, tight supply offset production gains
A new #USDA report projects that Ethiopia will continue importing about 1.4 million metric tons of #wheat despite increased domestic production, citing tight supply and surging prices. The report also notes that domestic wheat prices have risen sharply, reinforcing reliance on imports even as output grows.
Despite the expected growth in wheat production, the report warns that domestic wheat supplies remain tight, forcing millers and traders to increasingly rely on imports.
#Russia remains Ethiopia’s largest wheat supplier, accounting for 68 percent of imports, followed by #Ukraine and #Romania. Together, the three countries supplied 93 percent of Ethiopia’s wheat imports, underscoring the country’s continued reliance on Black Sea markets.
Prime Minister Abiy Ahmed has repeatedly remarked rejecting wheat import as a defining feature of Ethiopia........

News: USDA purchases #US wheat to support agricultural development in #Ethiopia and #Kenya
The United States Department of Agriculture (#USDA) has purchased 183,700 metric tons of U.S. hard red winter (HRW) wheat to support agricultural development projects in Ethiopia and Kenya, according to the U.S. Wheat Associates (USW).
The purchase, made in mid-January by the USDA’s Foreign Agricultural Service (FAS), marks the first U.S. wheat procurements under the Food for Progress program for the 2025 fiscal year.

🚀 USDA Maintains Soybean Production Forecast for 2025/2026
The United States Department of Agriculture (USDA) has maintained its forecast for the 2025/2026 soybean production at 4.262 billion bushels, unchanged from its March estimate. According to Jin10, the USDA also projects the ending stocks for the same period to be 350 million bushels, slightly above the market expectation of 349 million bushels, and consistent with the March forecast. Additionally, the USDA anticipates the soybean yield to remain at 53 bushels per acre, the same as the previous month's projection.
