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

🕵🏻‍♀️How Harvard rates your application? part 4 For part 1: https://t.me/farangizmurodiy/14 🏛 When you apply to Harvard, Harvard rates your application from 1 to 6 in four categories and gives one overall rating. Part 4: Athletic Rating 🏅🏅🏅 1️⃣Unusually strong prospect for varsity sports at Harvard, desired by Harvard coaches. 2️⃣ Strong secondary school contribution in one or more areas; possible leadership role(s). 3️⃣ Active participation. 4️⃣ Little or no interest. 5️⃣ Substantial activity outside of conventional EC participation such as family commitments or term-time work (could be included with other e/c to boost the rating or left as a "5" if it is more representative of the student's commitment). 6️⃣Physical condition prevents significant activity. Note: After watching lots of videos of Harvard students talking about their admission files, I understood that not being athlete will not damage your application, but if you're an international level athlete, it will benefit you a lot. Because the calculation of an application's overall rating is not just arithmetical, getting a low athletic rating will not disadvantage you if you are very successful in other areas. However, getting 1, being recruited athlete, will boost your application significantly. 👩🏻‍⚖️ This was the part 4 of#Harvard admission series. Finally, in the next Harvard post, I’ll be sharing strategies on how you can apply those valuable infos from all four parts to your own application. @farangizmurodiy

🕵🏻‍♀️How Harvard rates you? part 3 🏛 When you apply to Harvard, Harvard rates your application from 1 to 6 in four categories and gives one overall rating. Part 3: Personal Rating ❤️ 1) Outstanding 2) Very Strong 3) Generally Positive 4) Bland or somewhat negative or immature 5) Questionable personal qualities 6) Worrisome personal qualities 🤯 This is the most subjective rating in Harvard admissions. Also, this subjectiveness is the reason why Harvard is dealing with an affirmative action lawsuit. More info: https://rb.gy/tjr3zl What determines your personal rating is: 📝 Essays 👩‍🏫 Recommendation Letters Because it's very subjective, your application as a whole plays a role in this rating. Part 1: https://t.me/farangizmurodiy/14 Part 2:https://t.me/farangizmurodiy/23 👩🏻‍⚖️ This was the part 3 of 4 #Harvard admission series. In the end of the series, I’ll be sharing strategies on how you can apply this valuable info to your own application. @farangizmurodiy

🕵🏻‍♀️How Harvard rates you? part 2 🏛 When you apply to Harvard, Harvard rates your application from 1 to 6 in four categories and gives one overall rating. Part 2: Extracurricular Rating 🏆 1️⃣ Unusual strength in one or more areas. Possible national-level achievement or professional experience. A potential major contributor at Harvard. Truly unusual achievement. 2️⃣Strong secondary school contribution in one or more areas such as class president, newspaper editor, etc. Local or regional recognition; major accomplishment(s).[in another filing]: "Significant school, and possibly regional accomplishments: for example, an applicant who was the student body president or captain of the debate team and the leader of multiple additional clubs." 3️⃣Solid participation but without special distinction. (Upgrade 3+ to 2- in some cases if the e/c is particularly extensive and substantive.) 4️⃣ Little or no participation. 5️⃣Substantial activity outside of conventional EC participation such as family commitments or term-time work (could be included with other e/c to boost the rating or left as a "5" if it is more representative of the student's commitment). 6️⃣Special circumstances limit or prevent participation (e.g. a physical condition). 👩🏻‍⚖️ This was the part 2 of 4#Harvard admission series. In the end of the series, I’ll be sharing strategies on how you can apply this valuable info to your own application. @farangizmurodiy

🕵🏻‍♀️How Harvard rates you? When you apply to Harvard, Harvard rates your application from 1 to 6 in four categories and gives one overall rating. Part 1: Academic Achievement 📚 1) Summa potential: Genuine scholar; near-perfect scores and grades (in most cases) combined with unusual creativity and possible evidence of original scholarship. 2) Magna potential: Excellent student with superb grades and mid-to-high-700 scores (33+ ACT). 3) Cum laude potential: Very good student with excellent grades and mid-600 to low-700 scores (29 to 32 ACT). 4) Adequate preparation: Respectable grades and low-to-mid-600 scores (26 to 29) ACT). 5) Marginal potential: Modest grades and 500 scores (25 and below ACT). 6) Achievement or motivation marginal or worse. 👩🏻‍⚖️ This was the part 1 of 4 #Harvard admission series.
