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

Chapter 1:The cuckoo's nest The irksome sound coming from someone's radio , "it must be morning " i muttered , tho i dont usually wake up this early on a holiday like this , so i tried to cover myself in the warmth of blanket but not enough to insulate that annoying noise and so i gave up on my dream. The sun was dim today quite unusual day for a summer . A strong pingent smell caught my glemse , after using my brain and nose i was able to find the cordinates of its origin. "Its coming from my balcony "i shouted , I jumped out of my blanket and opened the balcony , There was a dead cuckoo lying on the floor , might have fallen from its nest . I usually come to see this cuckoo been feed by a small Canary , that was a quite appealing view to watch or rather entertaining. The decaying body of cuckoo was alluring alot of bugs and ants, "Someone will live on someone's death" i said on a quavering voice , My neighbour was also in his balcony watching that cuckoo's , his balcony was just 1 feet away from mine . Unlike me his balcony was been decorated with lot of flowers , pot were hanging on the side of his wall. A green fluffy carpet all over his wall, giving more athestic look to his balcony , on the other hand my balcony have alot of poops of the birds which i never bothered to clean , a rusty chair which got its rust by weting in the rain , some clothes hanging here and there , being just 1 feet away and paying the same rent there was a lot of difference in our balconies , or rather alot of difference in our personality . He usually come to water his plants tho we never talked before. After spending few more minutes in balcony gloring the blueness of sky , I went back to my room , my stomach was starving by the time , I quickly went to check on my fridge for something to eat , even my bad luck is unlucky ,it just contains some rotten yogurts , broken beer bottles , a pouch of sous which is expired , a frozen fish . I went to my kitchen and found that i was out of instant noodles too. #review #novel #suggestions
