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

🐺 **THE LAST GUARDIANS OF ETHIOPIA'S HIGHLANDS** 🏔️ *Africa's Rarest Predator on the Edge of Extinction* High in Ethiopia's Simien Mountains, where mist meets sky at 4,500 meters, lives the world's rarest wolf. Only 500 Ethiopian wolves remain - each one a living treasure of ancient Africa. **The Numbers Tell the Story:** ⚡ **Population**: Less than 500 individuals left on Earth 🏔️ **Habitat**: Highest-altitude wolves in the world 🎯 **Hunting**: 90% success rate targeting giant mole-rats 💰 **Tourism value**: $8,000-12,000 per wildlife expedition **Why This Matters:** Every Ethiopian wolf represents millions of years of evolution. These apex predators maintain the delicate balance of highland ecosystems while creating premium eco-tourism opportunities worth millions to local communities. *In Ethiopia's misty peaks, every wolf howl echoes the heartbeat of Africa's wild soul.* #EthiopianWolf#EndangeredSpecies#SimienMountains#WildlifeConservation#EthiopiaWildlife

🦊 ETHIOPIAN WOLF: THE LAST 500 ብር ተኵላ፡ የመጨረሻዎቹ 500 Beauty so rare, it hurts to watch. 💔 ━━━━━━━━━━━━━━━━ 💔 THE RAREST CANID ON EARTH ብር ተኵላ (Bir Tekula) - "Silver Wolf" Only 500 individuals left. In the entire world. ALL living ONLY in Ethiopia.🇪🇹 If they disappear from Ethiopia - they disappear FOREVER. ━━━━━━━━━━━━━━━━ 🔥 WHAT MAKES THEM SPECIAL 🎨APPEARANCE: • Red-rust coat shimmering in sun • White chest, long elegant legs • Amber eyes, intelligent gaze • Built for high altitude (3,000-4,500m!) 📍HABITAT: • Afro-alpine meadows • "Tundra at equator" (Sanetti Plateau) • Freezing nights, thin air • Extreme conditions 🎯BEHAVIOR: • Hunts giant mole rats • Diurnal (rare for canids!) • Social packs, monogamous pairs • Cooperative breeding ━━━━━━━━━━━━━━━━ 💪 GRACE IN MOTION Watch the video. 🎬 Slow motion reveals perfection: Every step - calculated Every leap - balletic Every landing - акробат's skill At 4,000m altitude where humans struggle... The Ethiopian Wolf THRIVES. "የተራራዎች ባለቤት" (Master of the mountains) ━━━━━━━━━━━━━━━━ 🇪🇹 WHY THIS MATTERS 💚FOR ETHIOPIA: • Symbol of unique biodiversity • National pride • Ecotourism jobs • Part of identity 🌍FOR THE WORLD: • Irreplaceable genetic heritage • Ecosystem health indicator • Reminder: extinction is forever "ብር ተኵላ የኢትዮጵያ ኩራት ነው" (Ethiopian Wolf is Ethiopia's pride) ━━━━━━━━━━━━━━━━ 😢 THE THREATS ❌ Habitat loss (agriculture expansion) ❌ Disease from domestic dogs (rabies - biggest threat!) ❌ Climate change impacts ❌ Genetic bottleneck (small population) But there is HOPE.💚 ━━━━━━━━━━━━━━━━ 💪 CONSERVATION IN ACTION 🛡️WHAT'S BEING DONE: ✅ Ethiopian Wolf Conservation Programme • Vaccination campaigns • Community education • Research & monitoring ✅ National Parks protection • Ranger patrols • Habitat preservation ✅ Community involvement • Local guardians • Tourism benefits shared ✅ International support • Wildlife organizations • Research partnerships ━━━━━━━━━━━━━━━━ 🌟 WHAT YOU CAN DO 💚SPREAD AWARENESS: Share this post - most don't know they exist! 📸RESPONSIBLE TOURISM: Visit Bale/Simien Mountains Support local ecotourism 💰SUPPORT CONSERVATION: Donate to Ethiopian Wolf Conservation Programme 🗣️SPEAK UP: Rare species need advocates "500 ብቻ። እያንዳንዱ አስፈላጊ ነው።" (Only 500. Each one matters.) ━━━━━━━━━━━━━━━━ 💔 WHICH FUTURE? Your grandchildren ask: "What was an Ethiopian Wolf?" You answer: "They used to run..."😢 OR "They still run free - and WE helped save them!"💪🇪🇹 Which future do YOU choose? ━━━━━━━━━━━━━━━━ 🦊 NOT A STATISTIC 500 beating hearts. 500 graceful hunters. 500 reasons to fight. Ethiopia's gift to the world. The world's responsibility to protect. "ብር ተኵላ - የዓለም ውበት" (Ethiopian Wolf - world's beauty) ━━━━━━━━━━━━━━━━ Watch them run. 🎬 Feel their grace. Understand their rarity. Then ACT.💪 Because 500 is not a lot. But it's enough to save. If we start NOW.⏰ ━━━━━━━━━━━━━━━━ 🌍 ETHIOPIA | ЭФИОПИЯ | ኢትዮጵያ 📱@ethiopia telegram #EthiopianWolf#Save500#CriticallyEndangered#BaleMountains#WildlifeConservation#EthiopiaPride#ProtectNature#EndangeredSpecies
