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. #trics#basic

🚀 Commodities to Outshine Stocks Amid Geopolitical and Economic Turmoil, Says Bank of America Strategist Bank of America strategist Michael Hartnett has indicated that investors should pivot towards the commodities market in the coming years, as this asset class is poised to benefit from global geopolitical and macroeconomic instability. According to Jin10, the ongoing Middle East conflicts and the race in artificial intelligence have heightened concerns over supply chains. Governments worldwide are striving to curb the soaring prices of energy and other natural resources, which impact industries and consumers, while also ensuring the supply of critical minerals like rare earths, essential for manufacturing and technology. Hartnett suggests that for the remainder of this decade, commodities will replace stocks as the primary choice for investors seeking to hedge against risks, inflation, and a weakening dollar. This shift is expected as investors move away from equities in favor of commodities, which are anticipated to become the biggest winners in the "buy anything but bonds" trade. The strategist also notes that excessive fiscal expansion could lead to more frequent bear market rallies in government bonds rather than sustained bull markets. #Commodities#Stocks#Geopolitics#Macroeconomics#Investment#Inflation#Energy#RareEarths#SupplyChain#AI#FiscalPolicy#MarketTrends
