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.

#UN rights office cites ‘widespread repression’ in #Uganda before next week’s presidential election The U.N. Human Rights Office said Friday that a presidential election in Uganda next week would be “marked by widespread repression and intimidation” against the opposition and others. Ugandan authorities in the East African country have used lawfare, including military legislation, to restrict the activities of politicians and others before voting on Jan. 15, the Geneva-based Office of the U.N. High Commissioner for Human Rights, or #OHCHR, said in a new report. “Next week’s elections in Uganda will take place in an environment marked by widespread repression and intimidation against the political opposition, human rights defenders, journalists and those with dissenting views,” OHCHR said. Ugandan police, the military and others have used live ammunition to disperse peaceful assemblies, & the security forces.... https://apnews.com/article/uganda-election-un-rights-report-1e30ab4e21419dad8cd73567fbc0759c

News: Rights groups warn #Ethiopia ‘on the brink’ of renewed large-scale conflict, call for urgent international action Twenty international as well as regional human rights and humanitarian organizations have warned that Ethiopia is “on the brink” of renewed large-scale conflict and called on the international community to take urgent action to prevent mass atrocities amid escalating violence across several regions. In an open letter dated 20 February 2026, the groups said ongoing and unresolved conflicts, entrenched impunity, and rising regional tensions are placing civilians at grave risk. They cited reports by the Office of the #UN High Commissioner for Human Rights (#OHCHR) of heavy weapons use, drone strikes, and arbitrary detentions, warning that space for de-escalation is rapidly shrinking. The signatories said there has been little meaningful progress toward durable conflict resolution in #Tigray, #Oromia, and #Amhara despite repeated .... Read more: https://addisstandard.com/?p=55309

News: #UN reports Over 6,000 killed in #Sudan’s El Fasher in three days as RSF took control At least 6,000 civilians were killed in just three days during an assault on the #Darfur city of #El_Fasher, according to a new report by the United Nations Office of the High Commissioner for Human Rights (#OHCHR). The report describes a wave of violence that has shocked human rights monitors, highlighting the scale of atrocities committed by Sudan’s Rapid Support Forces (#RSF) and allied militias. According to the report, the killings occurred between October 25 and 27, 2025, as RSF fighters and allied paramilitaries overran El Fasher. On October 26, the RSF, along with their allied Arab militias known as Janjaweed, seized control of el-Fasher, the Sudanese army’s last remaining stronghold in Darfur, and launched a violent campaign across the city and its surrounding areas after enduring... https://web.facebook.com/AddisstandardEng/posts/pfbid02rce3AMAVyevwjuMvSNrMmeUvRvqwS2SpH8NNMxkUz1sAonPfXdtmqpjpUvJpVtRhl
