Скорее всего уже слышали, что складывать строки через + это плохая практика. Падение производительности, и всё такое. Без лишних слов, давайте измерять: from timeit import timeit def t1(): # складываем 10 строк через + из переменной t = 'text' for _ in range(1000): s = t + t + t + t + t + t + t + t + t def t2(): # склеиваем список строк через метод join arr = ['text'] * 10 for _ in range(1000): s = ''.join(arr) def t3(): # складываем через + но не из переменной а непосредственно инлайн объекты for _ in range(1000): s = 'text' + 'text' + 'text' + ... # всего 10 раз Теперь каждую строку склейки запустим по 10М раз >>> timeit(t1, number=10000) 0.21951690399964718 >>> timeit(t2, number=10000) 1.4978306379998685 >>> timeit(t3, number=10000) 0.2213820789993406 Хм, а нам говорили что через "+" это плохо и медленно ))) 😁 Тут стоит учитывать, что речь идёт о склейке множества длинных строк. Давайте изменим условия: def t4(): t = 'text'*100 for _ in range(1000): s = t + t + t + t + t + t + t + t + t def t5(): arr = ['text'*100] * 10 for _ in range(1000): s = ''.join(arr) def t6(): for _ in range(1000): s = 'text'*100 + 'text'*100 + ... # всего 10 раз >>> timeit(t4, number=10000) 12.795130728000004 >>> timeit(t5, number=10000) 2.642637542999182 >>> timeit(t6, number=10000) 0.2184546610005782 Вот, уже другой разговор, сразу видна разница, в среднем в 6 раз. Но погодите, почему последний тест t6() по скорости такой же как и t3()? Ведь строки теперь в 100 раз длиннее! Это вопросы оптимизации кода, какие простые изменения ускоряют или замедляют выполнение программы. Мы столкнулись с примером обхода обращения к переменной. Например, именно так работает директива #define в С++, во время компиляции подставляя значение переменной вместо ссылки на неё. В Python это тоже работает, но часто ли вы сможете встретить такой способ работы со строками? К сожалению, способ почти только теоретический. В целом, тесты показали то, что мы хотели. Делаем выводы самостоятельно. Полный листинг 🌍 #tricks

💼Former U.S. Trade Representative Roy Kirk, who served in the Obama administration, has criticized President Donald Trump’s trade negotiations, warning that his aggressive style is creating confusion and hardship for American exporters. 🇺🇸 According to Kirk, Trump's pattern of threatening tariffs and then retreating after market backlash is doing more harm than good. 📉 🗣️“The president will be spooked by something, get a little bit upset, threaten more tariffs,” he said, adding that in the case of a negative reaction in the markets, he will then announce that “we’re on the precipice of a deal.” Kirk said this during his appearance on CNBC’s Squawk Box on Monday. 📺 See Also 👉Ronald Reagan ‘Didn’t Love Tariffs,’ Says Economist Paul Krugman: He Repeatedly Emphasized ‘The Virtues of Free Trade’ Kirk said that the unpredictable nature of U.S. trade policy under Trump is causing a lot of frustration among American companies that are trying to plan for the future. 🏭 ⚠️ The consequences of Trump’s “macho” trade tactics are being felt by ordinary exporters. 💬“They're having to pay the price for this macho,” he said, citing examples of soy farmers, cattle farmers, and other small businesses. 🌾🐄 #Trump#Tariffs#SmallBusiness 👂More on Trump's Ear ⚠️

Navigating AI Opportunities & Threats Explore how AI presents both challenges and opportunities for small businesses. While larger firms dominate the market, many entrepreneurs can thrive with modest revenue targets. AI could lead to the decline of SaaS businesses due to cost-effective alternatives. However, it allows individuals to quickly replicate and improve existing applications, catering to proven market needs. Though scaling to $500M ARR is tough in niches, a small investment can create meaningful products. Innovators can introduce multiple unique offerings, even in shadow of larger tech giants. #AI#SaaS#Business#Investment#Tech#Entrepreneurship#Revenue#ProductDevelopment#Innovation#Market#Growth#Web3#Startups#Opportunity#Threats#SmallBusiness#Investors#ExistingMarket#Applications#PMF#CostEfficiency
