R. David Murray added the comment: The data structure you are asking for bears a resemblance to the data structure used by the email package to record message headers. Email uses a list with a dict-like API cobbled together on top. The difference with your suggestion is that email also needs to record the order of the headers, so just having a list-of-values for each key isn't adequate. Any bets on whether or not we eventually run across a use of .ini format where the exact order of the duplicated keys within the whole list of keys matters? :)
With two use cases that could be served by the same data structure in the stdlib, I wonder if it is worth actually building the abstract data type. Probably not, but I thought I'd raise the possibility anyway :) ---------- nosy: +r.david.murray type: -> enhancement versions: +Python 3.5 -Python 3.4 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21329> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
