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

#TPLF welcomes #AU call for restraint, reaffirms commitment to dialogue The Tigray People’s Liberation Front (TPLF) has welcomed a call by the Chairperson of the African Union Commission, Mahmoud Ali Youssouf, urging restraint amid renewed tensions in Ethiopia’s Tigray region, reaffirming that dialogue remains the only viable path to resolving outstanding issues with the federal government. In a letter sent late on Saturday and addressed to the AU Commission Chairperson, the TPLF said it appreciates the African Union’s engagement in support of peace and stability in Ethiopia, noting that it takes “positive note” of the AU’s concern over recent developments in Tigray. The party further expressed its readiness to engage constructively in any dialogue initiative facilitated by the African Union, including through the AU High-Level Panel on Ethiopia, aimed at advancing “peace, confidence-building, and reconciliation.” https://addisstandard.com/tplf-welcomes-au-call-for-restraint-reaffirms-commitment-to-dialogue/

News: #Tigray rebels say #Ethiopian troops preparing for war Ethiopian federal authorities are preparing "to wage a war against Tigray," a senior official from this northern regional state told AFP on Wednesday, raising fears of a new conflict. Tigray emerged in 2022 from a two-year war that saw federal forces, backed by militias and the Eritrean army, clash with rebels from the Tigray People's Liberation Front (#TPLF). The TPLF dominated Ethiopian politics for some 30 years before current Prime Minister Abiy Ahmed, a non-Tigrayan, took power in 2018. At least 600,000 people were killed in the conflict, according to estimates from the African Union. A ceasefire held for more than two years, but clashes between federal and Tigrayan forces broke out again in November 2025 and January 2026. Large numbers of federal troops have for several weeks been massed at the Tigray border, where.... https://web.facebook.com/AddisstandardEng/posts/pfbid023a9Gk4wS4Zc9q1exiF73ypsGSrQ1ubLT6Pg7Hv5gRNoJDmMEsv8KpNyvcM73Nq8il

#Op_ed: Ghosts of Governance: Opposition paralysis, failure of political imagination in post-war #Tigray The most dangerous moment for a post-war society is when paralysis becomes normal, “a condition that has gripped Tigray for too long,” writes Getachew Gebrekiros Temare. He argues, “War destroyed infrastructure, displaced millions, and shattered institutions,” yet the deeper crisis remains political. Factionalism within the #TPLF and fragmentation among opposition parties have left society without coherent leadership. Opposition rhetoric often functions as controlled dissent rather than driving meaningful change. He notes, “The cumulative consequences of fragmentation, pseudo-analysis, and political hesitation are now impossible to ignore.” Getachew emphasizes that the solution requires “the emergence of a political movement grounded in public interest rather than personal ambition.” https://addisstandard.com/?p=55998
