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

photorealistic tall-format scene in Ralph Lauren rustic-luxury style. A woman with long, beautifully coiffed black hair stands by a large-paned window inside a refined, moody room. She wears a flowing satin gown and robe, gazing at a violent storm outside. The storm is fierce and foreboding, with trees bending in the wind, swirling leaves, heavy rain slashing against the window, and distant lightning illuminating a stormy night sky. The room is warm and opulent, lit by soft candlelight and a glowing fireplace. Equestrian and vintage Americana decor--dark wood, leather armchairs, and brass accents. Color palette: deep navy, burgundy, forest green, warm amber. Mood: cinematic, gothic, powerful, a sanctuary against the untamed storm --ar 3:4 --style raw --v 6.1 by daci_zaha #fantasy 📣Midjourney prompts

A cosmic void with a glowing green portal slowly opening. The portal’s edges shimmer with crackling energy, and ghostly, tentacle-like forms begin to emerge. The scene is filled with swirling, otherworldly clouds in shades of green and purple, creating a hypnotic vortex effect. In the foreground, a solitary cultist stands on a jagged rock outcrop, arms raised toward the portal in supplication. The camera captures the moment from a low angle, emphasizing the grandeur of the portal and the cultist’s insignificance in comparison. The lighting is surreal, with the portal casting eerie shadows across the landscape. --ar 16:9 --v 6.1 by nsihi_01366 #fantasy 📣 Midjourney prompts

A foggy Victorian-era forest with a hidden ancient stone altar covered in strange, glowing runes. A horned shadow looms over the altar, barely visible through the mist. The atmosphere is tense and foreboding, with twisted trees forming claw-like shapes and the ground littered with broken branches. – sepia filter, Victorian horror, haunting and mystical --ar 16:9 --v 6.1 by max3en #fantasy 📣 Midjourney prompts

A close-up portrait of a mystical figure with a dual persona. One side of their face is adorned with intricate golden armor, detailed with elegant patterns and flourishes. The other side is engulfed in dark, organic shadows that resemble living flames or smoky tendrils, blending seamlessly into their skin. Their eyes are strikingly different: one a piercing, icy blue and the other a fiery, intense amber. The figure’s gloved hands, dark and clawed, frame their face as they look forward with a mix of allure and mystery. Soft, wavy hair cascades around them, highlighted by warm lighting that contrasts beautifully with the darkness. The mood is surreal and fantasy-inspired, blending beauty and darkness with high detail and dramatic lighting --ar 9:16 --v 6.1 by boombamblum1 #fantasy 📣 Midjourney prompts
