Not really, but it depends who is doing it and why. If you have a piece of code that is only going to be maintained by people speaking French, with French keyboards, then why not use French words for identifiers? That includes those French letters with accents. Python 3 lets you do so. Silly bits of code like Ⅳ = 4 (or worse, Ⅳ = 9) should be avoided because they are silly, not because they are illegal. That's about the same as using: eine, zwei, drei, vier, fünf = range(1, 6) in code intended to be read by English speakers, only even harder to type. Remember that programmers *discourage* most misspellings of words (with a few exceptions, usually abbreviations): number_of_pages = 42 is preferred to: nombar_off_paiges = 42 But for non-English speakers, most languages *force* them to either write code in Foreign (foreign *to them*), or to misspell words. Allowing Unicode identifiers means that they can write in their native tongue, using correct spelling, *if they so choose*. Of course, if you want your code to be readable world-wide, stick to English :) -- Steven _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
