Eric V. Smith added the comment: I think the best way to approach this is to generate (in code) all of the places where string prefixes appear. There's StringPrefix, endpats, triple_quotes, and single_quoted.
With the currently valid combinations of f, b, r, and u, I count 24 combinations: ['B', 'BR', 'Br', 'F', 'FR', 'Fr', 'R', 'RB', 'RF', 'Rb', 'Rf', 'U', 'b', 'bR', 'br', 'f', 'fR', 'fr', 'r', 'rB', 'rF', 'rb', 'rf', 'u'] If I add "fb" strings (plus raw), I count 72 combinations: ['B', 'BFR', 'BFr', 'BR', 'BRF', 'BRf', 'BfR', 'Bfr', 'Br', 'BrF', 'Brf', 'F', 'FBR', 'FBr', 'FR', 'FRB', 'FRb', 'FbR', 'Fbr', 'Fr', 'FrB', 'Frb', 'R', 'RB', 'RBF', 'RBf', 'RF', 'RFB', 'RFb', 'Rb', 'RbF', 'Rbf', 'Rf', 'RfB', 'Rfb', 'U', 'b', 'bFR', 'bFr', 'bR', 'bRF', 'bRf', 'bfR', 'bfr', 'br', 'brF', 'brf', 'f', 'fBR', 'fBr', 'fR', 'fRB', 'fRb', 'fbR', 'fbr', 'fr', 'frB', 'frb', 'r', 'rB', 'rBF', 'rBf', 'rF', 'rFB', 'rFb', 'rb', 'rbF', 'rbf', 'rf', 'rfB', 'rfb', 'u'] Coding these combinations by hand seems insane. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25311> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
