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 🤓

The Trump administration has quietly removed a Pride flag from the Stonewall National Monument in Manhattan.
The flag’s removal follows new federal guidance issued by the Department of the Interior on Jan. 21 that restricts the display of unauthorized flags at National Park Service sites. Under the order, only U.S. flags or congressionally authorized flags may be raised on NPS flagpoles. Manhattan borough president Brad Hoylman-Sigal told The New York Times the Trump administration’s order directly led to the Pride flag’s disappearance from the Greenwich Village site, which marks the birthplace of the modern LGBTQ rights movement. Stonewall became the nation’s first federally recognized LGBTQ historic site in 2016, commemorating the 1969 police raid that sparked days of protests and helped launch the gay rights movement. Hoylman-Sigal said he and other local officials plan to raise the Pride flag again on Thursday, despite potential backlash. “We may be prevented from doing so,” he told the outlet, “but if we don’t seize this moment, and this outrage, I think we’ll let down generations of queer activists.” The Daily Beast has reached out to Brad Hoylman-Sigal for comment.

Trump announced that he was reopening psychiatric clinics that the Democrats had closed out of tolerance for psychos.
This is a very bold move, given the fact that a huge percentage of Americans today are obviously mentally ill. Trump is leading the way to gradually send transgender and LGBTQ+ there. This is a subproject of MAGA called MAHA - Let's Make America Healthy Again. Trump starts with psychiatry, as this is where the cases are most neglected.

Nothing to see here. That's just bloody clown and a drag queen Zelensky is dancing on high hills.

🇺🇦🏳🌈🏳⚧A Ukrainian LGBT+ recruitment campaign video turned to be a video from the campaign for gay marriage in the UK in 2012.

美国同性婚姻占各州人口比例
楼主还注释道 DC 更像是个城市，所以写了 Vermont 是“最高”的州。
在评论里注释了城市的比例，但其实按城市算 DC 也远超其它城市……排除之后，毫不意外三番第一，波特兰和西雅图紧随其后，在传统红州的奥兰多、迈阿密（佛州）和奥斯丁（德州）也名列前茅。
