Brace expansion does not currently exist in Python's glob. You'd have to use a third party module to expand the braces and then run glob on each returned pattern, or use a third party module that implements a glob that does it for you. Shameless plug: Brace expansion: https://github.com/facelessuser/bracex Glob that does it for you (when the feature is enabled): https://github.com/facelessuser/wcmatch Now whether Python should integrate such behavior by default is another question.
