there is no str.isspecial()

[Skaperen]

there is no str.isspecial() method that i can find. is there some short alternative?

[metulburr]

>>> import string
>>> string.punctuation
'!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'

[Skaperen]

i was looking for it to see what they claimed to be special characters in python3 to see if it included any new unicode ones.

[nilamo]

Are unicode characters "special"?  They probably shouldn't be.

You've also some special groups like emoticons and modifiers which have been applied on the text above @http://www.eeemo.net/

there are many unicode characters above 128 that don't fit under alphabet or numeric.

Don't forget multiple byte codes, utf-16le, utf-32 etc

[sparkz_alot]

Are you concerned what Python considers a special character, or what unicode (specifically utf-8) considers special?

what Python considers a special character.  if they just let it be up to unicode then, fine.  i wish they would, at least, have proper tests for them, as a convenience.  if they provide one class, then IMHO they should provide all classes, so there isn't a mix of sources.

i didn't forget they exist.

does python3 use them for string types?  the bytes types are apparently 8-bit and thus utf-8.  the string type has to be using something or have some means that lets it abstract a wide range of numerical values.  i wrote this code that lets users work with these values numerically at the command line.  it takes a numeric value for one character per argument and outputs the utf-8 sequence.  i wrote it so i could output specific unicode in shell scripts (i can already do this in python).  it includes a function named intx() that accepts numeric values in many base prefixes (like '0y' for base 32, ':' for base 36, '0t' for base 3, '0q' for base 4) that is used to encode digits from each argument.  try this command to test it, if you have Linux.
