Функция sub в regex может принимать функцию в качестве аргумента repl.
📄 Из документации:
If repl is a function, it is called for every non-overlapping occurrence of pattern. The function takes a single match object argument, and returns the replacement string.
То есть для каждого совпадения будет вызвана функция для вычисления замены вместо замены на одну и ту же строку для всех совпадений.
Иными словами, для замены разных совпадений на разные строки не потребуется запускать re.sub() много раз для каждой строки замены. Достаточно определить функцию, которая вернёт строку для каждого из совпадений.
Описание слишком запутанное🤔, давайте лучше рассмотрим на простом примере:
Создаем карту замены. То есть какие строки на какие требуется менять.
remap = {
'раз': '1',
'два': '2',
'три': '3',
'четыре': '4',
'пять': '5',
}
Пишем функцию поиска строки для замены. Единственным аргументом будет объект re.Match.
Используя данные этого объекта мы вычисляем замену on-the-fly!
def get_str(match: re.Match):
word = match.group(1)
return remap.get(word.lower()) or word
Пример текста.
text = '''Раз Два Три Четыре Пять
Вместе будем мы считать
Пять Четыре Три Два Раз
Мы считать научим вас
'''
Теперь запускаем re.sub и вместо строки замены (repl) подаём имя функции.
(Данный паттерн ищет отдельные слова в тексте)
>>> print(re.sub(r'(\w+)', get_str, text))
1 2 3 4 5
Вместе будем мы считать
5 4 3 2 1
Мы считать научим вас
Думаю, достаточно наглядно 🤓

🚀 Zcash Open Development Lab Unveils Strategic Direction Focused on Post-Quantum Security
On April 13, Zcash Open Development Lab (ZODL) founder Josh Swihart announced the latest developments for Zcash, emphasizing a strategic direction centered on post-quantum security, scalability, and user experience. According to BlockBeats, Swihart likened the initiative to the Artemis II lunar mission, highlighting the pursuit of seemingly impossible goals through technological breakthroughs. The ZODL team revealed that Zcash is entering the 'Zcash IV' phase, aiming to build infrastructure akin to a 'lunar base' to support the protocol and applications' secure expansion to billions of users, while advancing the vision of privacy transactions without large-scale financial surveillance.
On the product and technology front, ZODL continues to iterate, with its 3.3.x version now available on iOS and Android, featuring new hardware wallet connection management, SDK upgrades, and multiple user experience enhancements. Key developments include advancing Keystone wallet functionality and upgrading the address system (ZIP 316, UIVK/UFVK). Meanwhile, the Zcash core team has addressed several system issues and is progressing with the Zallet alpha version development, strengthening unified address standards and wallet interaction experience to lay the foundation for future scalability and performance improvements.
Additionally, ZODL disclosed ongoing growth in application data and participation in a stablecoin privacy summit to enhance industry collaboration. However, due to increased regulatory and network restrictions, ZODL has temporarily removed its app from Russian app stores. The team emphasized that privacy is not optional but a fundamental need in the digital age, and they will continue to accelerate delivery pace to promote ZEC adoption and ecosystem development.
The core of Zcash Open Development Lab is to develop an open, self-custodial private financial platform, aiming to expand ecosystem interoperability through collaboration and bring protected ZEC transactions to the global mainstream market.
