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

#Surkhandarya🦂 Humane Science: Student from Termez Develops a Way to Extract Scorpion Venom Without Killing It A third-year biology student at the Termez State Pedagogical Institute, Feruza Tukhtamurodova, has developed an innovative device that allows scorpion venom to be extracted without harming the animal. 🔬 Unlike traditional methods that often result in the death of the scorpion, this new approach uses safe electrostimulation. It enables repeated venom extraction from the same scorpion, without causing harm. 💡 Why it matters: — reduces the killing of animals — helps address the shortage of valuable biological material — opens new opportunities for medicine and pharmaceuticals 🧪 Scorpion venom is not just dangerous — it has significant medical potential. It contains chlorotoxin, which can slow the growth of cancer cells, as well as neurotoxins used in treating neurological disorders. 💰 Interesting fact: On the global market, scorpion venom can cost up to $12,000, while in Uzbekistan it is around $5,000. 🌱 This innovation shows that science can be both effective and humane. 👏 Proud of Uzbekistan’s young scientists! ☘️Read the latest environmental news on the @ekologuz page.

#Surkhandarya#Official_Response Earlier, our channel reported a case of cruel treatment by two individuals towards a desert tortoise listed in the Red Data Book of Uzbekistan. Following this incident, the Surkhandarya Regional Department of Ecology and Climate Change, together with officers of the internal affairs bodies and the National Guard, conducted оперативe investigation measures. The investigation revealed that the incident took place in April of this year. The individuals involved were identified as residents of the “Yangikuch” mahalla in Denov district — citizens N.J. and A.S. During the inquiry, citizen N.J. admitted guilt, stating that the act was committed unknowingly. (However, this raises a question: how can a mentally sound adult harm a living creature “unknowingly”?) Based on the case, the Denov District Department of Internal Affairs imposed an administrative penalty on N.J. under Article 111 of the Code of Administrative Responsibility of the Republic of Uzbekistan. A fine of three base calculation units was issued, amounting to 1,236,000 soums. The State Committee for Ecology and Climate Change of Uzbekistan reminds that cruelty to animals is strictly prohibited and entails liability in accordance with the law.
