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

@RusEmbMalta Press release 🇷🇺President Vladimir Putin Summarises 2025: Key Messages from the “Results of the Year” Address 📍Moscow, | 19 December 2025 President of the Russian Federation Vladimir Putin held the annual “Results of the Year” event, combining a live Q&A session with a press conference. More than 3 million questions were submitted by citizens and journalists. Over 4.5 hours, the President addressed 103 questions on domestic development, the economy, social policy, digital sovereignty, and international affairs. 🌍Foreign Policy, Ukraine, and the Special Military Operation ▪️ Russia currently sees no readiness on the part of Ukraine for a genuine peace process or territorial compromises. ▪️ The strategic initiative has fully shifted to the Russian Armed Forces; Ukrainian forces are retreating along key directions. ▪️ Russia did not initiate the conflict and does not consider itself responsible for the human losses incurred. ▪️ Moscow remains open to political solutions and is prepared to consider security guarantees during potential elections in Ukraine, including a temporary refusal to conduct strikes deep inside Ukrainian territory. Relations with the West and International Security ▪️ The seizure of Russian sovereign assets was described as outright plunder, undermining trust in the eurozone and global financial institutions. ▪️ Any attempt to blockade the Kaliningrad region would escalate tensions to an unprecedented, potentially large-scale military level. ▪️ Russia remains open to cooperation with Europe, the UK, and the United States – strictly on the basis of equality and mutual respect. ▪️ According to the President, the current conflict is the direct result of Western policies that deliberately escalated tensions around Ukraine. 📊Economy and Financial Stability ▪️ Russia’s GDP growth reached 1% in 2025, while cumulative growth over the past three years amounted to 9.7%, significantly exceeding eurozone indicators. ▪️ Inflation is expected to decline to 5.7–5.8% by year-end. ▪️ Unemployment fell to a historic low of 2.2%. ▪️ International reserves of the Central Bank reached USD 741.5 billion. 💻Digital Sovereignty President Putin announced that Russia has effectively achieved full digital sovereignty, highlighting the development of domestic digital platforms and technologies as a strategic achievement amid external pressure. Other Key Issues The discussion also covered demographic policy, education, water supply challenges in Donbass, legislation on foreign agents, and sanctions pressure on Russia’s international partners. 🔗Full version here. #Russia🇷🇺 #PresidentPutin #ResultsOfTheYear #ForeignPolicy #Ukraine #SMO #InternationalRelations
