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

UK's AI Copyright Debate: Balancing Innovation and Creative Rights The UK government has launched a consultation exploring legal frameworks for AI training on copyrighted material, proposing four policy options with significant implications for AI and creative industries. 1️⃣Controversial Proposal: One option would allow AI firms to use copyrighted works without rights holders’ permission, even for commercial purposes, with minimal restrictions. This has sparked concerns among creatives about irreversible harm to their industries. 2️⃣Alternative Frameworks: Other proposals include opt-out systems for copyright holders or stricter licensing requirements, but creatives argue these approaches lack enforcement and transparency, leaving copyright holders vulnerable. With feedback open until February 25, 2025, this consultation is a critical moment for shaping the intersection of AI innovation and intellectual property rights in the UK. #AIRegulation#Copyright#AIEthics#UKPolicy

🇬🇧UK Reconsiders AI Copyright Exception After Industry Backlash The UK government has stepped back from plans to allow AI companies to freely use copyrighted material for training by default. The proposal would have permitted data scraping unless rights holders explicitly opted out. The reversal follows objections from prominent figures in the creative industries, including Paul McCartney, Elton John, Coldplay, Richard Curtis, Antony Gormley, and Ian McKellen. Science minister Liz Kendall stated that consultations with stakeholders — including creatives, AI firms, unions, and academics — led the government to abandon a preferred policy option. #AIRegulation#Copyright#AIethics#UKpolicy#IntellectualProperty

🇬🇧UK DSIT Warns Businesses on AI Cybersecurity Risks The UK Department for Science, Innovation and Technology (DSIT) issued an open letter warning businesses about the growing availability of AI models with cybersecurity vulnerability detection capabilities. The department stated that such systems create new risk exposures for organizations as these tools become more accessible. DSIT referenced releases by Anthropic and OpenAI, as well as subsequent reviews by the AI Security Institute. The department noted that the UK “is not standing still in response to this threat,” but emphasized that government action alone will be insufficient. Business leaders were urged to adopt preventive measures to stay ahead of emerging model capabilities. #AIRegulation#Cybersecurity#AISafety#UKpolicy#RiskManagement
