Nah, Python already solves that for you:
py> s = "১২৩৪৫.৬৭৮৯০"
py> for c in s:
... print(unicodedata.name(c))
...
BENGALI DIGIT ONE
BENGALI DIGIT TWO
BENGALI DIGIT THREE
BENGALI DIGIT FOUR
BENGALI DIGIT FIVE
FULL STOP
BENGALI DIGIT SIX
BENGALI DIGIT SEVEN
BENGALI DIGIT EIGHT
BENGALI DIGIT NINE
BENGALI DIGIT ZERO
py> float(s)
12345.6789
Further to my earlier post, if you call:
for sep in ",u\00B7u\066B":
mystring = mystring.replace(sep, '.')
before passing it to float, that ought to cover just about anything you
will find in real-world data regardless of language. If Ethan finds
something that isn't covered by those three cases (comma, middle dot and
Arabic decimal separator) he'll likely need to consult an expert on that
language.
Provided Ethan doesn't have to deal with thousands separators as well.
Then it gets complicated.
