Tim Peters added the comment: It's fine. Read the docs. "s.insert(i, x) inserts x into s at the index given by i (same as s[i:i] = [x])"
Note that: >>> fred[-1:] [4] So the empty slice s[-1:-1] is _between_ 3 and 4 in `fred`. If you're not surprised by >>> fred[-1] 4 then you shouldn't be surprised by what `fred.insert(-1, whatever)` does either ;-) ---------- nosy: +tim.peters resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28423> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
