В продолжение прошлого поста про цифры в мире строк. Почему методы isdigit() и isnumeric() не определяют в строке float и отрицательные значения? Дело в том, что эти методы работают с ЦИФРАМИ, то есть с единичным символом. А строка "-2" или "3.4" это уже ЧИСЛО. То есть не символ а значение, записанное несколькими символами. Все озвученные методы проходятся по каждому символу строки и проверяют их индивидуально. В юникоде есть символы цифр с точками "🄀⒈⒉⒊⒋⒌⒍⒎⒏⒐" Каждая из них это ОДИН СИМВОЛ, поэтому он будет считаться цифрой >>> '⒌'.isdigit(), '⒌'.isnumeric() True, True Но когда мы пишем это выражение в два символа ( 5+точка), то это не работает. >>> '5.'.isdigit(), '5.'.isnumeric() False, False А еще есть такие символы >>> '⑴⑵⑶⑷⑸'.isdigit() True >>> '🄁🄂🄃'.isdigit() True Но они не преобразуются в десятичные цифры >>> '⒈'.isdecimal() False >>> '🄃'.isdecimal() False >>> '⑶'.isdecimal() False #basic

🎙 Address by Ambassador of Russia to South Africa Roman Ambarov on the occasion of Mandela Day (July 18,2025) 💬 Dear friends, On July 18, we celebrate #MandelaDay – a holiday officially declared by the United Nations to honor the legacy of the South African statesman and one of the most outstanding champions of human rights, Nelson Mandela. The name Mandela is, without exaggeration, familiar to every person living in the former Soviet republics. For two decades, the slogan “Freedom for Mandela!” echoed through the media and peaceful demonstrations, while our country remained the only major power that consistently refused to engage with the criminal racist regime. 👉 The Soviet Union not only provided substantial financial support to the South African liberation movement but also assisted in training military personnel. Nelson Mandela praised #RussiaSouthAfrica ties in the times of the struggle against apartheid: "In a difficult time, Russia became a second home for many of us. Hundreds of young South Africans received an education here — an opportunity denied to them in their own country. Many of our cadres received military training that turned them into skilled fighters for freedom and justice. <...> For the help in liberating the entire South African nation from an inhumane system, we say from the bottom of our hearts: 'Spasibo bolshoe!'" [Thank you very much in Russian]. The friendship forged in those challenging times for South Africans continues to live on between our nations today — thanks in no small part to Nelson Mandela himself. At the heart of Mandela Day, as established by the UN, lies a principle of action, not words – people are encouraged to perform acts of charity and help those in need. The Russian Embassy in South Africa fully embraces this spirit: as part of this commemorative occasion, Russian diplomats will provide assistance and support to three South African children social facilities. 🤝 I extend my warmest congratulations to all our South African friends on this special day and wish you well-being, prosperity, and strength in pursuing your ideals. #MandelaDay2025
