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

https://www.coursera.org/specializations/data-science-python?utm_medium=email&utm_source=marketing&utm_campaign=2QBGEJZREeajEnVsu251ig The 5 courses in this #University of #Michigan specialization introduce learners to data science through the python programming language. This skills-based specialization is intended for learners who have basic a python or programming background, and want to apply statistical, machine learning, information visualization, and text analysis techniques to gain new insight into their data. Introduction to Data Science with Python (course 1), Applied Plotting, Charting & Data Representation in Python (course 2), and Applied Machine Learning in Python (course 3) should be taken in order and prior to any other course in the specialization. After completing those, courses 4 and 5 can be taken in any order. All 5 are required to earn a certificate.

Quando la vi*lenza diventa strumento di politica estera, prima o poi ritorna a bussare alle porte di casa. Le gu*rre combattute lontano, la retorica della libertà usata come maschera di interessi economici, l’addestramento alla disumanizzazione: tutto ciò si traduce oggi in una società che implode sotto il peso delle proprie stesse contraddizioni. La lezione è chiara: ciò che un impero esporta, inevitabilmente lo eredita. #guerra#michigan#detroit#attualita#news#oggi#america

Chipotle Michigan Unionization with Teamsters (3 years & 6 months on) August 2022, workers at a Chipotle in Lansing, Michigan, voted 11-3 to unionize, becoming the first and only employees at the chain to ever win union recognition. Three years later, they still don’t have a contract. After years of bargaining, the Chipotle corporation and Teamsters have indefinitely paused negotiations, and workers no longer anticipate a collective bargaining agreement at their store. https://jacobin.com/2026/02/chipotle-unionization-michigan-teamsters-organizing \#Chipotle#LabourMovement#MIchigan#Organize#Teamsters#Unions https://redd.it/1r8f9ni @r_iww
