Оператор pipe позволяет писать более компактный код, реализуя логику объединения данных (Union). Важно помнить, что его поведение зависит от контекста. Побитовые операции (логическое OR) result = 5 | 3 # 5 (0101) | 3 (0011) = 7 (0111) Самое главное - не путать с оператором or, это другое! Объединение множеств set_a = {1, 2, 3} set_b = {3, 4, 5} set_c = set_a | set_b # {1, 2, 3, 4, 5} set_c |= {5, 6} # {1, 2, 3, 4, 5, 6} Слияние словарей dict_1 = {"a": 1, "b": 2} dict_2 = {"b": 3, "c": 4} merged = dict_1 | dict_2 # {'a': 1, 'b': 3, 'c': 4} merged |= {"d": 5} # {'a': 1, 'b': 3, 'c': 4, 'd': 5} Аннотации типов, заменяет Union def process_data(value: int | str) -> None: print(value) Допустимо использовать в isinstance или issubclass isinstance(3, int | float) # True Паттерн-матчинг status_code = 404 match status_code: case 200 | 201 | 204: print("OK") case 400 | 404 | 500: print("ERROR") Для использования в своих классах требуется переопределить метод __or__ Так же нашел библиотеку pipe которая добавляет еще много возможностей. Рекомендую ознакомиться ;) #basic

🚀 Ethereum Layer 2 Network Scroll Faces Overcharging Issue Ethereum Layer 2 network Scroll has reportedly overcharged users by more than $50,000 in transaction fees over approximately four days. According to ChainCatcher, this occurred after the Scroll team manually increased two rate multipliers in their gas price oracle six times within six days, each time raising them by 2 to 10 times. This adjustment cumulatively increased the L1 data cost parameter to 1,280 times its original benchmark. Approximately 139,000 transactions were affected, with the total cost originally estimated at around $280, but users were charged over $50,000. The majority of these transactions were automated by bots. L2BEAT clarified that the overcharging was not due to a sequencer issue but resulted from multiplier adjustments executed through a multi-signature wallet by the team. This incident has raised questions about whether Scroll previously subsidized users with below-cost rates to maintain activity. Data from DeFiLlama indicates that Scroll's total value locked (TVL) currently stands at $24 million, a significant decline of 96% from its peak of $585 million in October 2024. As of the time of reporting, Scroll has not publicly responded to the issue. #Ethereum#Layer2#Scroll#Overcharging#GasFees#Blockchain#DeFi#TVL#CryptoNews#TransactionFees#ETH#SCR
