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

🚀 Significant RAVE Token Movement Detected Amid Price Surge On April 10, two addresses suspected to belong to the same entity transferred 18.58 million RAVE tokens to a centralized exchange (CEX) 10 hours prior to a significant price increase. According to BlockBeats On-chain Detection, this transaction occurred when the token's price was $0.43, totaling $8 million. The current value of these tokens has risen to $19.08 million. The funds for these transactions originated from two sources: a withdrawal from the CEX and the RAVE token deployment address. #RAVE#Cryptocurrency#TokenTransfer#PriceSurge#OnChainAnalysis#Blockchain#CEX#CryptoTrading

🚀 ZEC Experiences Significant Price Surge Amid Whale Activity ZEC has seen a notable price increase since April 8, according to Hyperliquid data. The cryptocurrency accelerated from approximately $269, achieving a 43.1% rise over two days. As of today, the price peaked at $385 and is currently reported at $367.5, marking a 24-hour increase of 15.7%. According to BlockBeats On-chain Detection, during this surge, whales who shorted before April 8 have incurred significant losses. Among the whales opening new million-dollar positions today, most are following the upward trend, with only one address, 0x931, taking a contrary short position. This short position was opened with a 10x leverage, amounting to $3.44 million at an average price of $365.8, with a liquidation price of $411.5. Additionally, the address has set take-profit and stop-loss orders at $350 and $411, respectively. #ZEC#Cryptocurrency#PriceSurge#WhaleActivity#Blockchain#CryptoTrading#OnChainAnalysis#LeverageTrading

🚀 Bitcoin's Current Volatility May Present a Generational Buying Opportunity Cryptocurrency analyst Ali Martinez recently shared an analysis on the X platform, suggesting that instead of debating whether Bitcoin has hit its bottom, attention should be focused on whether the current volatility presents a 'generational buying opportunity.' According to Odaily, Martinez identifies key 'value zones' for the current cycle based on long-term trend lines, on-chain liquidity, and cost distribution indicators. The UTXO Realized Price Distribution (URPD) indicates a significant concentration of holdings between $63,111 and $70,685, forming the primary support band. If Bitcoin falls below $63,111, the market may enter a liquidity vacuum. From a long-term perspective, Bitcoin is nearing a critical ascending trend line from the past decade, approximately between $56,000 and $60,000. Historically, this position has often marked the accumulation phase before significant price increases. In more extreme scenarios, the CVDD indicator suggests a structural bottom around $47,960, while the MVRV 0.8 range at approximately $43,647 indicates a market in an 'extreme pain' phase, typically associated with exhaustion of selling pressure. In the event of a black swan event, prices could briefly dip to an extreme range of around $36,657. Based on these zones, Martinez employs a dollar-cost averaging (DCA) strategy, gradually increasing positions across different support bands to reduce overall holding costs. He believes the market is currently in a phase of low sentiment, but potential opportunities are gradually emerging. #Bitcoin#Cryptocurrency#CryptoTrading#MarketAnalysis#Volatility#InvestmentOpportunity#DCA#OnChainAnalysis#CryptoMarket#TradingStrategy#BTC

Bybit Hack Linked to Lazarus Group A recent analysis suggests the Bybit hack, involving ~$1.5 billion, may have been conducted by the North Korean Lazarus Group. Arkham Intelligence reports that the group likely converts ERC-20 tokens to ETH, then to BTC, possibly funding nuclear programs. Research also points to potential links with a previous attack on Phemex. Investigators note that funds were moved to wallet 0x33d0...8F65 during the laundering process.
