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

Bangladesh Could Find Itself Heading for Huge Changes The Bangladesh Nationalist party (BNP) led by Tarique Rahman has claimed a sweeping victory in the country’s first election since a gen-Z uprising toppled the autocratic regime of Sheikh Hasina. By Friday morning, results had shown a clear win for the BNP, returning them to power after 20 years. The vote had been seen as the first free and fair election held in Bangladesh for almost two decades and came after a period of significant political upheaval in the country. This victory was expected,” said Salahuddin Ahmed, a leading BNP committee member. “It is not surprising that the people of Bangladesh have placed their trust in a party … capable of realising the dreams that our youth envisioned during the uprising.” Ahmed acknowledged a difficult task lay ahead for the new BNP government, which has pledged a new era of democracy and zero tolerance towards corruption. “This is not a time for celebration, as we will face mounting challenges in building a country free from discrimination,” he said. By about midday local time, the BNP had won 208 seats while their rival, the Islamist party Jamaat-e-Islami, had claimed 69 seats. India was among the first countries to congratulate the BNP. Relations between the two neighbours had plummeted since the fall of Hasina and the message from Indian prime minister, congratulating the BNP on their “decisive” win, was seen to extend an olive branch to the new government. “India will continue to stand in support of a democratic, progressive and inclusive Bangladesh,” said Modi, adding that he was looking forward to working with Rahman. Rahman, who returned to Bangladesh in December after 17 years of exile in London, is now poised to become the country’s next prime minister. He comes from one of the country’s most powerful political dynasties; the son of former prime minister Khaleda Zia and former president Ziaur Rahman, who was assassinated in 1981. The election was the first truly competitive vote in years. As documented for years by human rights groups and the UN, Hasina’s regime routinely suppressed dissent of its critics and political opponents, thousands who were disappeared, tortured and killed in secret jails. Many emerged only after Hasina was toppled. The past three elections under Hasina were marred by widespread allegations of vote-rigging. The student-led uprising that toppled Hasina’s 15-year regime in August 2024 had been prompted by mounting anger over widespread corruption, human rights abuses and an economic slump. The uprising, and Hasina’s brutal crackdown on anti-government protesters, left an estimated 1,400 people dead, according to the UN. For the past 18 months, the country has been run by an interim government under Bangladesh’s only Nobel laureate Muhammad Yunus, who was tasked with readying the country for free and fair elections. Speaking after casting his vote in Dhaka, Yunus said that the country had “ended the nightmare and begun a new dream.” #bangladesh#changes#hasina#corruption#rahman 📱American Оbserver - Stay up to date on all important events 🇺🇸
