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 🤓 #libs#regex

Journey to Fluency

#weird-truth @fluencyinenglish 🔹Old Funeral Customs: Placing Coins on the Eyes of the Dead @fluencyinenglish At Stillinger Family Funeral Home in Greenfield, Indiana, we get questions all the time about old funeral customs like this one: What’s the meaning of placing coins on the eyes of the dead? Like many customs and traditions, this one goes way back – in this case to the times of Greek mythology. Placing coins on the eyes of the dead was intended to “pay the ferryman”. Let’s take a closer look at this old funeral custom: ❇️Paying the Ferryman @fluencyinenglish According to often accepted interpretations of Greek mythology, it was essential to pay the ferryman. What does this mean? Charon was the name of a mythological boatman who would transport the souls of the departed across the River Styx; in essence, this was a journey from the land of the living to the land of the dead. To ancient Greeks and others, not making this journey meant not passing on to the afterlife, but instead remaining behind to wander the banks of the River Styx. Because Charon needed to be paid for the journey, coins were placed on the body. @fluencyinenglish In the Mouth or On the Eyes? It appears the earliest manifestations of paying the ferryman called for placing a single silver or gold coin under the tongue of the dead. This was called Charon’s Obol (the obolus was a silver coin in ancient Athens, Greece). The custom eventually came to include the alternative practice of placing a coin ON the mouth of the deceased, as opposed to under the tongue. @fluencyinenglish It is not exactly clear when the tradition evolved to include the practice of placing two coins on the eyes of the departed. Modern iterations of this practice may call for placing pennies or quarters on the closed eyes. It is also believed that placing coins on the eyes of the dead was historically done to make sure the eyes remained closed – out of the superstitious fear that looking into the eyes of the deceased would reveal our own death. @fluencyinenglish From Timeless Traditions to Modern Funeral Services While many old funeral traditions – such as placing coins on the eyes of the dead – may be regarded as outmoded superstitions with no basis in fact or science, many people still regard them as comforting customs to help them find peace with the passing. @fluencyinenglish
