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

💡Did you know?Not everyone pays personal income tax – it depends on how much you earn. Singapore uses a progressive tax system: tax rates start at 0% for chargeable income below $20,000 and increase as income rises. Those who earn more contribute more, making the system fairer for everyone. That spirit of fairness was at the heart of our conversations with close to 30 youths this week. The Tax Youth Network (TYN) held its second kick‑off session at the refreshed Taxpayer and Business Service Centre (TBSC), bringing together students, young professionals and aspiring tax leaders for candid conversations on Singapore’s tax system. The room buzzed with thoughtful questions, diverse perspectives and discussions on trust, fairness and the role taxes play in nation-building. The new Discovery Hub at TBSC also made its debut, creating a more open and engaging space for these conversations. We were also privileged to have our partners, Singapore Chartered Tax Professionals and the Tax Academy of Singapore, share insights on career pathways and learning opportunities in the tax ecosystem. 👉🏻 TYN is more than a network, it is a community of youth advocates shaping perspectives and driving conversations on Singapore’s tax future.

It simplifies WebRTC by providing a smaller, simpler alternative to Google's library, with compatibility for browsers like Firefox and Chrome. You can use it to connect native apps directly to web browsers with minimal dependencies, supporting secure connections via GnuTLS, Mbed TLS, or OpenSSL. It also supports compiling to WebAssembly for browser use, making it flexible for cross-platform real-time communication development[1][4]. This helps you build fast, efficient apps for video, audio, or data sharing without heavy libraries. https://github.com/paullouisageneau/libdatachannel
