У строки в Python есть два очень похожих метода. На столько похожих что кажется они делают одно и тоже. Это метод isdigit() и isnumeric() Давайте посмотрим зачем нам два одинаковых метода? И так ли они одинаковы? Очевидно что isdigit() говорит нам, состоит ли строка только из чисел 0-9 >>> '12'.isdigit() True >>> '12x'.isdigit() False >>> '-12'.isdigit() False >>> '12.5'.isdigit() False Можно предположить что isnumeric() делает более глубокий анализ и распознаёт в строке float или отрицательное число. >>> '15'.isnumeric() True >>> '-15'.isnumeric() False >>> '15.2'.isnumeric() False Нет, всё так же как и с другим методом. В чем же тогда разница? Для начала посмотрим следующие примеры: >>> '5'.isdigit(), '5'.isnumeric() # Обычная цифра 5 # True, True >>> '꧕'.isdigit(), '꧕'.isnumeric() # Яванская 5 # True, True >>> '෩'.isdigit(), '෩'.isnumeric() # Синхала 3 # True, True >>> '৩'.isdigit(), '৩'.isnumeric() # Бенгальская 3 # True, True >>> '༣'.isdigit(), '༣'.isnumeric() # Тибетская 3 # True, True >>> '³'.isdigit(), '³'.isnumeric() # 3 верхний индекс (степень) # True, True >>> '𝟝'.isdigit(), '𝟝'.isnumeric() # Математическая двойная 5 # True, True >>> '๔'.isdigit(), '๔'.isnumeric() # Тайская 4 # True, True >>> '➑'.isdigit(), '➑'.isnumeric() # 8 в круге # True, True А теперь примеры в которых, по мнению Python, результаты не равны >>> '¾'.isdigit(), '¾'.isnumeric() # дробь три четверти # False, True >>> '⅕'.isdigit(), '⅕'.isnumeric() # дробь одна пятая # False, True >>> '𒐶'.isdigit(), '𒐶'.isnumeric() # клинопись 3 # False, True >>> '三'.isdigit(), '三'.isnumeric() # 3 из унифицированной идеограммы # False, True >>> '⑩'.isdigit(), '⑩'.isnumeric() # цифра 10 в круге # False, True >>> 'Ⅳ'.isdigit(), 'Ⅳ'.isnumeric() # Римская 4 # False, True >>> '𑇪'.isdigit(), '𑇪'.isnumeric() # Сенегальская архаическая 10 # False, True >>> '𐌢'.isdigit(), '𐌢'.isnumeric() # Этрусская цифра 10 # False, True >>> 'ↂ'.isdigit(), 'ↂ'.isnumeric() # Римская цифра 10000 # False, True >>> '〇'.isdigit(), '〇'.isnumeric() # Символ ККЯ ноль # False, True Получается, что isdigit() говорит нам, является ли символ десятичной цифрой или спецсимволом, имеющим цифирное значение после преобразования. В свою очередь isnumeric() включает все дополнительные символы юникода которые имеют отношения к числовым и цифровым представлениям. Ну и пара примеров в которых в обоих случаях символ не является числом, это эмодзи. >>> '🕙'.isdigit(), '🕙'.isnumeric() # эмодзи 10 часов # False, False >>> '7️⃣'.isdigit(), '7️⃣'.isnumeric() # эмодзи 7 # False, False Также есть еще один дополнительный и весьма полезный метод isdecimal(). Он нам сообщает, можно ли из указанного символа сделать простую десятичную цифру. То есть сработает ли метод int(x) >>> '෩'.isdecimal(), int('෩') # Синхала 3 # True, 3 >>> '➑'.isdecimal(), int('➑') # 8 в круге # False, ValueError Какие выводы? 🔸 При определении цифры в строке isdigit() подходит лучше чем isnumeric(), но оба не гарантируют успешную конвертацию в int 🔸 Для однозначного определения возможности преобразования строки в int лучше подходит метод isdecimal() 🔸 Для однозначного определения символов 0...9 лучше использовать regex Полный список символов юникода которые определяются как numeric #basic

🎙 Foreign Minister Sergey Lavrov’s remarks at the meeting with delegation of the Permanent Committee of the International Conference of Asian Political Parties (Perm, May 29, 2025) 💬 Sergey Lavrov: Dear colleagues, dear friends, This is the year when the International Conference of Asian Political Parties commemorates its 25th anniversary. And because of their reputation and their authority, they are a platform for exchanging views and experience in the context of party-to-party cooperation. Cooperation at this level is one of our priorities. It's a very useful addition to the so-called classical diplomacy and that contributes a lot to promoting mutual trust, mutual understanding between peoples. The creation of the conference is a signal, a very clear signal to the entire world. And very timely response to reconsider the place of the Asian countries in international and global developments. We assess very positively the increase of the political work of your conference. And we see with pleasure the sustainable process of expanding your influence in the continental architecture, in the architecture of regional organizations, some of which are experiencing erosion of their influence, if not degradation, since they abandoned practically all of the key principles of the UN Charter. I have in mind such organizations on our Eurasian continent as the European Union, which became more Euro-Atlantic than Eurasian following NATO. <...> In the last 10-15 years, all these principles including equal and indivisible security, including the statement that no one, be it the country or organization, should prepare to dominate in Europe, all this was abandoned, violated. 🌐 We need Eurasia of course. And by the way, Eurasia is the biggest, the richest continent. The continent which, unlike Africa and Latin America, is home of several world civilizations with thousands and thousands of years of history. <...> #Eurasia is the only continent which doesn't have any universal continental structure, like African Union in Africa, like CELAC in Latin America. We have quite a lot, many integrational movements, organizations which address security issues, like Shanghai Cooperation Organization, #ASEAN, Collective Security Treaty Organization (#CSTO), Commonwealth of Independent States (#CIS) and the Gulf Cooperation Council (#GCC), the South Asian Association for Regional Cooperation (#SAARC) and there is no umbrella. We are very much in favor of promoting party-to-party dialogue. Our ruling party, United Russia, in cooperation with other parliamentary parties and their fractions is promoting very actively this kind of cooperation. And I will highlight the initiative of United Russia of last year, when they convened a meeting of various parties to consider methods of fighting the new forms of colonialism and neo-colonialism. <...> A movement created on the basis of the conference, which is called "Freedom of Nations". ☝️ The inadmissibility of neo-colonial forms of exploitation is one of the agenda items of the Group of Friends of the UN Charter. Last year, we initiated, through this group, the resolution of the UN Committee on Decolonization. The draft resolution supported by this committee was accepted by the UN General Assembly. <..> A clear majority supported it. The idea is to announce the 14th of December, the day of the adoption of The Declaration on the Granting of Independence to Colonial Countries and Peoples of 1960, as a date of fighting the new forms of neo-colonialism. Сolonial exploitation was very blunt. Slaves, you know, digging the resources and leaving the countries in very poor condition. If you take the economic system in the world, countries, especially in Africa, mostly produce, they provide natural resources to the western countries We would like to promote the movement to resolve this injustice. Without fighting any country, we never want to isolate any country from cooperation, but cooperation must be based on equal footing, just principles. 🤝 We express our readiness to cooperate with your conference.
