Заметка начинающим, которые часто сталкиваются с подобной непоняткой. Ситуация следующая, есть список файлов: names = [ 'image.bmp', 'second.txt.bkp', 'data.db', '.config.cfg', 'file.ext.bkp' ] И мы хотим убрать у них окончание ".bkp". Не знаю зачем, пример довольно надуманный) Но суть он показывает, а это главное. Те, кто еще не очень знаком с библиотекой os.path или pathlib, вероятно решат обработать имена как строки. И тут вполне подойдет метод строки strip(). Что делает этот метод? Он отрезает указанные символы по обеим сторонам строки. Если ничего не указать, то убирает невидимые символы (пробелы, табуляции и переносы строк). В нашем случае будет выглядеть вот так: >>> name.strip('.bkp') То есть просим удалить строку '.bkp' по краям имени файла, если таковая есть. Можно применить аналогичный метод rstrip(), чтобы отрезать только справа, но для этого примера используем обычный. >>> for name in names: >>> print(name.strip('.bkp')) image.bm second.txt data.d config.cfg file.ext Хм, что-то не то с нашими именами! Что случилось??? Видим нежелательное переименование в именах, где и близко не было указанной строки '.bkp' А дело всё в том, что данный метод ищет не указанную строку, а указанные символы, и не важно в каком порядке. Для метода strip() строка '.bkp' это не паттерн для поискаа список символов. Потому он отрезал симовол 'p' от '.bmp' и удалил точку из файла '.config.cfg'. Как тогда правильно заменить именно паттерн? Для начинающего можно посоветовать метод строки replace(), который как раз использует для замены указанную строку целиком. В нашем примере заменим её на пустую строку. >>> for name in names: >>> print(name.replace('.bkp', '')) image.bmp second.txt data.db .config.cfg file.ext Уже лучше, но помните, это лишь пример про strip(). Для работы с именами файлов есть способы и более "правильные", дающие однозначно верный результат. Я взял файлы только в качестве примера. Даже replase() тут может сделать не то что ожидаем. Просто впредь будьте внимательны с этим strip(). #basic

🚀 AI Technology Presents New Opportunities Amid Potential Financial Crisis On April 13, Liquid Capital founder Yi Lihua expressed optimism about the potential resolution of ongoing conflicts, noting that motivations for continued warfare are diminishing. According to BlockBeats, Yi emphasized that peace negotiations typically evolve from disagreement to consensus, suggesting that the conflict may gradually come to an end. He remarked that both sides have no reason to continue fighting, and the moment an agreement is reached could signal a positive market shift. Yi highlighted that, in the medium to long term, the market is anticipating a potential large-scale financial crisis. He observed defensive strategies in the financial sector, such as major capital holding high cash ratios and sovereign entities increasing gold reserves. In this context, if another crisis occurs, it will be a crucial test for Bitcoin's status as a safe-haven asset and may offer significant opportunities for low-level investment. Furthermore, Yi Lihua believes that AI technology is creating new opportunities for talented entrepreneurs. He noted that small teams can develop global products, reducing costs associated with financing and organizational management. Experienced serial entrepreneurs, in particular, should seize the opportunities presented by this "AI Age of Exploration." #AI#FinancialCrisis#Investment#Bitcoin#Entrepreneurship#Innovation#MarketOpportunities#Technology#PeaceNegotiations#GlobalProducts#BTC

Ethereum ETF Sees Major Inflows The Ethereum spot ETF recorded a net inflow of $139M last week, with Blackrock's Ethereum ETF, ETHA, gaining $135M. However, on January 27, the crypto market saw declines across sectors, with DeFAI down 28.73%. Other sectors like AI Agents saw a 16.91% drop. U.S. crypto czar David Sacks noted ongoing evaluations regarding Bitcoin and digital assets. Meanwhile, Rosseti, Russia's state power company, plans to introduce Bitcoin mining to leverage idle power resources. Runetoshi's new memecoin, Runes, faced volatility, dropping from $28M to $500k in market value. Arthur Hayes predicts Bitcoin could dip to $70,000 before a future rise to $250,000 this year.

🚀 North Sea Oil Prices Surge Amid Refinery Competition and Strait Concerns Oil prices in the North Sea have reached unprecedented levels as European and Asian refineries compete for supplies. According to BlockBeats, the Financial Times reported on April 10 that the ongoing control of the Hormuz Strait by Iran has further fueled market concerns. Data from the London Stock Exchange Group (LSEG) indicates that the spot price for Brent North Sea Forties crude oil approached $147 per barrel on Thursday, surpassing the peak seen before the 2008 financial crisis. This price is significantly higher than the international benchmark Brent crude June futures contract, which is priced around $50, highlighting signs of a shortage in the oil market. Traders have noted that the price surge, exceeding $30 per barrel, has hit the threshold set by the Intercontinental Exchange (ICE), preventing them from purchasing next week's Brent crude contracts for difference (CFD). These contracts are commonly used to hedge against rising oil prices. #NorthSeaOil#OilPrices#RefineryCompetition#StraitConcerns#HormuzStrait#BrentCrude#OilMarket#LSEG#FinancialCrisis#OilShortage#ICE#CFD
