Небольшой трик с регулярными выражениями который редко вижу в чужом коде. Допустим, вам нужно распарсить простой текст и вытащить оттуда пары имя+телефон. Вернуть всё это надо в виде списка словарей. Возьмем очень простой пример текста. >>> text = ''' >>> Alex:8999123456 >>> Mike:+799987654 >>> Oleg:+344456789 >>> ''' Соответственно, для выделения нужных элементов будем использовать группы. Получится такой паттерн: (\w+):([\d+]+) Как мы будем формировать словарь из найденных групп? >>> import re >>> results = [] >>> for match in re.finditer(r"(\w+):([\d+]+)", text): >>> results.append({ >>> "name": match.group(1), >>> "phone": match.group(2) >>> }) >>> print(results) [{'name': 'Alex', 'phone': '8999123456'}, ...] Можно немного сократить запись используя zip >>> results = [] >>> for match in re.finditer(r"(\w+):([\d+]+)", text): >>> results.append(dict(zip(['name', 'phone'], match.groups()))) Но есть способ лучше! Это именованные группы в regex. Можно в паттерне указать имя группы и результат сразу забрать в виде словаря. >>> for match in re.finditer(r"(?P<name>\w+):(?P<phone>[\d+]+)", text): >>> results.append(match.groupdict()) То есть всё что я сделал, это добавил в начале группы (внутри сбокочек) такую запись: (?P<group-name>...) Теперь найденная группа имеет имя и можно обратиться к ней как к элементу списка >>> name = match['name'] Либо забрать сразу весь словарь методом groupdict() >>> match.groupdict() #tricks#regex

🌎 China’s Three Gorges Dam is the world’s largest hydroelectric power station. Completed in 2012, it spans the Yangtze River and displaced over 1.3 million people. The reservoir stretches about 600 kilometers, flooding numerous cities and archaeological sites. ✨ #engineering⚡#environment⚡#hydropower 👉subscribe Interesting Planet

🚀 Bhutan's Bitcoin Mining Activities May Have Slowed Amid Economic Pressures Bhutan may have halted or reduced its Bitcoin mining operations after selling 70% of its Bitcoin holdings. According to Foresight News, this move contrasts with other major institutions and sovereign nations that are increasing their cryptocurrency and gold reserves. Bhutan's hydropower is reportedly being redirected to supply electricity to neighboring India rather than being used for Bitcoin mining. Economic pressures, along with declining Bitcoin prices, increased network difficulty, and halving pressures, are squeezing mining profitability. As of now, Druk Holding and Investments, the sovereign wealth fund managing Bhutan's Bitcoin assets, has not publicly commented on any asset transfers or the status of its mining operations. #Bhutan#Bitcoin#Cryptocurrency#BitcoinMining#Hydropower#EconomicPressure#SovereignWealthFund#MiningProfitability#India#DigitalAssets
