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: Preparedness is vital’: #Tigray President warns against ‘living in defeat’ at Emperor Yohannes IV commemoration During the 137th anniversary of the martyrdom of #Emperor_Yohannes IV, Lieutenant General #Tadesse Wereda, President of the Interim Administration of Tigray, delivered a sobering address, emphasizing that while peace remains the priority, the region must remain prepared for any eventuality.

"We are carefully nurturing the relative peace we have in our hands," President Tadesse stated. "However, there are circumstances where forces beyond your capacity emerge, forcing you to make decisions you would not otherwise choose." In a pointed message regarding the region's security & political stance, the President underscored that peaceful options must...... Read more: https://addisstandard.com/?p=55799

#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 .....
