Updates: Status: Accepted Labels: Milestone-Release0.6.5 Comment #1 on issue 1376 by ondrej.certik: sum doesn't works for lists of symbols http://code.google.com/p/sympy/issues/detail?id=1376
the sum() is meant to be used like this: In [5]: sum(1/x, (x, 1, 4)) Out[5]: 25 ── 12 In [6]: sum(1/x, (x, 1, oo)) Out[6]: Sum(1/x, (x, 1, oo)) But I agree it's a serious problem that we have overridden the built-in sum and changed the signature. Do you have some idea to fix this? In any case, we should fix this in the next release. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
