Цифры 0 1 2 3 4 5 6 7 8 9 — это не единственные символы, которые считаются цифрами. Python следует правилам Unicode и считает «цифрами» сотни различных символов. Вот полный список таких символов.
Это влияет на такие функции, как int, unicode.isdecimal и даже re.match:
# Пример 1 int('෯') # Вывод: 9
# Пример 2 '٢'.isdecimal() # Вывод: True
# Пример 3 import re bool(re.match(r'\d', '౫')) # Вывод: True

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
How Does Telegram Make Money?
Telegram is a free app and runs on donations. According to a blog on the telegram: We believe in fast and secure messaging that is also 100% free. Pavel Durov, who shares our vision, supplied Telegram with a generous donation, so we have quite enough money for the time being. If Telegram runs out, we will introduce non-essential paid options to support the infrastructure and finance developer salaries. But making profits will never be an end-goal for Telegram.
