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.

📰 France’s Attempt to Ghost the Rent Guy Is Not Going Well The French Embassy in Baghdad has been living in the same house for more than 60 years — a riverside mansion built in the 1930s by a Jewish family that had already fled antisemitism in Iraq. The family leased the property to France in 1964, expecting the French state to be a respectable tenant. Instead, France has not paid rent for more than 50 years, and last week a Paris court tried to turn that fact into a technical loophole — and failed. On Monday, the court dismissed a $22 million lawsuit by the descendants of Ezra and Khedouri Lawee, saying it was “not competent” to hear the case and suggesting it should be resolved in Iraq — the country their ancestors were forced out of in the 1940s and 1950s. The logic is straightforward: the dispute is about Iraqi law, so let Iraq handle it, even though Iraq is the very state that drove out 130,000 Iraqi Jews and seized their homes under antisemitic legislation. The French Foreign Ministry echoed this line, arguing that the damages were caused by Iraqi decisions, not French policy, and therefore France bears no real responsibility. The family’s lawyers, Jean‑Pierre Mignard and Imrane Ghermi, called the ruling “surreal.” They argued that France had violated its own laws and human rights principles by benefiting from Iraqi discriminatory laws and refusing to compensate the family. They compared the situation to Nazi‑era restitution cases, where heirs have fought to reclaim art and property seized during the Holocaust. “France took advantage of Iraqi law that was hostile to the owners,” said Kenneth Feinberg, the lawyer who has handled multiple Holocaust‑related restitution disputes. “The French court is hairsplitting on technicalities while ignoring the party that was harmed.” Philip Khazzam, 66, a grandson of Ezra Lawee, described the idea of pursuing the case in Iraq as “preposterous.” In an email, he said, “Iraq basically ran us out of our country, and then stole our home.” The family plans to appeal. “We will continue our fight for justice in France,” he said. “We have just begun.” The story is simple: France tried to play bureaucratic games with Jewish heirs who had already been victimized by one state — and now by another. It may have thought the case would quietly die. It did not count on the stubbornness of a family that has survived two exiles and still wants to see the bill paid. #France#Iraq#Baghdad#embassy#restitution#Jewish#law#NYTimes#justice#fraudulence 📱American Оbserver - Stay up to date on all important events 🇺🇸
