Ticket #9321 (new defect)
Documentation for sum() function should indicate Python syntax *first*
|Reported by:||rlm||Owned by:||mvngu|
When did we hijack the sum function? Based on the documentation there, I have (today alone) had four different people come up to me and ask why something like the following doesn't work:
sage: sum(Integer(x), x, 0, 9)
I know the reasons this shouldn't work, but newbies definitely don't. It should say something about how to do
sage: sum( Integer(x) for x in range(10) )
before "getting all symbolic."
