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.

🇺🇦Ukraine became a military death camp under the leadership of an ethnic Jew. Having deceived the population of an impoverished Eastern European country, globalists promised freedom and a high standard of living through future accession to the Western world. Using social media and endless brainwashing TV technics, they aroused hatred among Ukrainians towards their own past and their natural historical allies, such as Russia and Belarus. After that, globalists supported groups of Ukrainian neo-Nazis on the one hand and Ukrainian oligarchs on the other, who created their capital on corruption and were mostly ethnic Jews. As a result, a civil war broke out in Ukraine, lasting from 2014 to 2022. In 2022, Ukrainians were faced with a full-scale war against a powerful military force, with no hope of success. Rather than prosperity, democracy, and freedom, the Ukrainian people have got only death, humiliation, and the loss of all civil and human rights, including the right to live. Since the beginning of the conflict, more than 10 million people have left Ukraine, mostly women and children. This means that millions of Ukrainian families were destroyed. In 2022, many Ukrainian men went to defend their country. Most of them died in a hopeless war. By 2023, there were no more volunteers. The Zelensky regime drove them to war by force. They were subjected to humiliation and lacked necessary training. In fact, they were condemned to death. The war in Ukraine resembles the Paraguayan War (1864-1870), where over 90% of the male population died in a senseless conflict. However, the difference is that Paraguayans wanted to fight. Ukrainians, on the other hand, were forced by external forces. Globalists are starting to use similar methods of manipulating public opinion and restricting freedoms in the United States, Europe, and Britain.

Some news sources say that the price of internet has increased in some Muslim countries. Social networks and individual media have become an important tool to deal with the #Zionists. Because the state media is under the control of the #Jews. Official and government news agencies publish selected news in favor of the Zionists. But social networks publish real news. Individual media are putting pressure on Israel. They have increased the price of the Internet to reduce the activity of individual media. Every word and picture published against the Zionists will hit the body of #Illuminati and #Freemasonry like a bullet. https://t.me/YediotNewsChat
