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

A study on men found that eating garlic made their body odor smell more pleasant, more attractive, and less intense. Researchers collected sweat samples and had others rate the smell. Note: The study tested sweat, not their breath.🤪 🧄👃🧪 [Read more] @googlefactss #ScienceFacts#DidYouKnow#HumanBody#Research If you have ideas or feedback contact us: @Googlefactss_Feedback_bot

The human digestive system is about 7–9 meters (23–30 feet) long. The small intestine measures about 3–7 meters (10–23 feet), and the large intestine is about 1.5 meters (5 feet) long. Food typically takes 24 to 72 hours to travel from the mouth to the toilet. This time can differ depending on what you eat, how much water you drink, and how active you are. 🧠📏⏱️ [Read more 1] [Read more 2] @googlefactss #HumanBody#DigestiveSystem#ScienceFacts#DidYouKnow

A brain freeze happens when something very cold touches the roof of the mouth or the back of the throat. This causes blood vessels in that area to quickly narrow and then widen again. This change activates a nerve that sends pain signals to the brain, which is why the pain is felt in the head. The sensation usually lasts only a few seconds to about a minute. 🧊🧠⚡ [Read more] @googlefactss #BrainFreeze#HumanBody#ScienceFacts#Health If you have ideas or feedback contact us: @Googlefactss_Feedback_bot

Babies are born with around 30,000 taste buds. Adults have about one-third of that number. This means babies can taste more flavors than grown-ups. As people get older, they lose many taste buds, which changes how they experience food. 👶🍎 [Source] @googlefactss#TasteBuds#Babies#ScienceFacts

Psychopaths, often called ‘evil,’ lack empathy and guilt. They were once seen as untreatable. New studies show therapy like CBT and computer training can reduce violence and help them feel empathy. Treatment is limited but promising. 🧠💡 [Read more] @googlefactss#Psychopathy#Therapy#MentalHealth#ScienceFacts

Women outperform men in recognizing all faces, with a particular advantage for female faces. 👩🦰👨🦱 They recognize both male and female faces better than men do. Men do not show this same bias toward their own gender. [New Link1] [New Link2] @googlefactss#Psychology#FaceRecognition#GenderDifferences#ScienceFacts

Ants don't have lungs. They breathe through tiny holes along the sides of their bodies called spiracles. These connect to a network of tubes (tracheae) that deliver oxygen directly to their tissues. [Read more] @googlefactss #Ants#Biology#Entomology#ScienceFacts

People who eat the mushroom Lanmaoa asiatica raw or undercooked have reported seeing tiny human-like figures moving around them. These are called lilliputian hallucinations. Reports from people across different cultures and backgrounds describe similar details, including small figures walking on floors and furniture. The effects can begin 12–24 hours after eating and may last 1–3 days. Some cases are serious and require hospital care.

15 December 1970, Venera-7 became the first spacecraft to land on Venus and send data back to Earth. Despite problems, it transmitted temperature information for 23 minutes after landing. The mission showed that Venus has extreme heat and pressure. [Source] @googlefactss #Venera7🚀#Venus🌍#SpaceExploration#ScienceFacts

Serge Voronoff performed experiments transplanting testicle tissue from monkeys into men and boys to try to improve health and vitality. He also grafted testicle tissue onto female goats in his research. These practices were done in the early 1900s but later found to be ineffective and controversial. 🙈✂️⚽️⚽️ [Read more] @googlefactss #SergeVoronoff#MedicalHistory#Transplants#ScienceFacts

Pregnant women have one more organ than non pregnant women. The placenta is a temporary organ that grows in the uterus during pregnancy. It connects the mother and baby through the umbilical cord. It gives the baby oxygen and nutrients and removes waste like carbon dioxide. It also makes hormones that help the pregnancy continue and lets helpful antibodies pass to protect the baby. "Fun" fact: After birth, the placenta leaves the body. Some people keep it and even consume it.. 🤰👶🍽 [Read more] [Don't eat it] #placenta#pregnancy#humanbody#sciencefacts#biology@googlefactss

Isaac Asimov was born on January 2, 1920. He wrote the Three Laws of Robotics: 1. Robots can't harm humans or let them be harmed. 2. Robots must follow human orders unless it breaks the first law. 3. Robots must protect themselves unless it breaks the first or second law. 🤖📜 [Read more] @googlefactss #IsaacAsimov#Robotics#ThreeLaws#ScienceFacts
