[issue26483] docs unclear on difference between str.isdigit() and str.isdecimal()

Martin Panter added the comment: “digits which do not form decimal radix forms” I see you have taken this from a Unicode document, but “forming a form” seems a long way of saying very little. The difference seems a bit vague, but I gather that digits not in the Unicode “decimal digit” category

Julien added the comment: To dig further, the DIGIT_MASK and DECIMAL_MASK used in `unicodeobject.c` are from `unicodectype.c` and they match values from `unicodetype_db.h` witch is generated by `Tools/unicode/makeunicodedata.py` which built those masks this way: # decimal digit, integer d

Anna Koroliuk added the comment: Hi, all! At Helsinki Python sprint I with the kind help of Ezio found two things. 1) This code gives results which are attached in the file. I will just now show some interesting cases where isdigit() and isdecimal() give different results. for c in map(chr,

Serhiy Storchaka added the comment: AFAIK ‘general category “Nd” ’ is the same as ‘the property value Numeric_Type=Decimal’. Yet one related predicate is str.isnumeric(). https://docs.python.org/3/library/stdtypes.html?#str.isnumeric Return true if all characters in the string are numeric cha

[issue26483] docs unclear on difference between str.isdigit() and str.isdecimal()

Martin Panter added the comment: The documentation could certainly be clarified to say that all decimals, as determined by isdecimal(), are also digits as determined by isdigit(). IMO the current documentation is confusing or wrong to stay that decimals ‘include digit characters’; it is actual

[issue26483] docs unclear on difference between str.isdigit() and str.isdecimal()

Serhiy Storchaka added the comment: Yes. For details you need to read The Unicode Standard. And every decimal character is accepted by the int() constructor, but non-decimal digits are not. >>> for d in decimals: x = int(d) ... >>> for d in set(digits) - set(decimals): ... try: ...
