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.

#Ethiopia: #Tigray Interim Administration rejects Tselemti return model, reaffirms commitment to IDPs and territorial claims President of the Tigray Interim Administration, Lt. Gen. Tadesse Werede, has rejected the approach used to facilitate the return of internally displaced persons (#IDPs) to #Tselemti, describing it as counterproductive and warning that it should not be replicated elsewhere. Speaking in Shire Endaselasie during celebrations marking the Feast of the Trinity, Lt. Gen. Tadesse said the experience in Tselemti had become “a conspiracy that is causing Tigray to lose,” according to local media reports. He stressed that, even in the name of peace, the administration would not abandon efforts to ensure the return of displaced persons or relinquish what it considers Tigray’s territorial claims. In December 2025, Addis Standard reported that IDPs returning to the war-affected districts of Tselemti, Laelay Tselemti, and Mai Tsebri in .... Read more: https://addisstandard.com/?p=54613

News: “#Ethiopia inches ever closer to war” – The Economist Ethiopia is edging closer to another devastating conflict as renewed tensions in the #Tigray region raise fears of a wider regional conflagration, The Economist magazine reported in its this week edition. A TPLF official cited by the magazine said the Ethiopian National Defense Force was “mobilising in full force,” warning that another war could be catastrophic if political restraint fails. Tensions spiked again when TPLF-linked forces crossed the #Tekeze River into #Tselemti last week. While officials said the move was intended to protest the treatment of returning civilians, some analysts cited by The Economist believe it may also have been aimed at testing federal defenses... The African Union publicly offered to mediate on 30 January, but Ethiopia privately rejected the proposal, telling the #AU to refrain from intervening in its internal affairs, according to sources cited by The Economist.

#Ethiopia: Interim President says dialogue under #Pretoria Agreement remains possible as #Tigray forces withdraw from Tselemti Tigray advanced forces have withdrawn from #Tselemti in what the Tigray Interim Administration described as a confidence-building measure aimed at demonstrating readiness for dialogue and a peaceful resolution to the current tensions, Interim President Lt. General #Tadesse said. “Our withdrawal shows clearly that we have no desire to return to war,” General Tadesse said, adding that “there is no question that can be answered by war, but by peace and negotiation.” Speaking on Saturday to Tigrai Television, he stressed that the situation does not have to escalate into full-scale conflict, emphasizing that dialogue remains both possible and preferable. The Interim President said Tigray’s core demands remain unchanged, centering on the return of internally displaced persons (#IDPs) and the restoration .....
