[issue42895] Return multi-line list concatenation without parentheses returns only first operand

JD-Veiga added the comment: What a shame. I forget that + is also a unary operator. That produces a new logical line with correct identation though never executed. Sorry for the inconvenience.⁶ -- ___ Python tracker <https://bugs.python.

New submission from JD-Veiga : I was trying to return the concatenation of several lists from a function but, inadvertently, forgot to surround the multi-line concatenation expression with parentheses. As a result, the function returns just the first operand and does not perform

algorizm to merge nodes

share the same name, all these nodes need be merged. For example, ['a', 'b'], ['a', 'g'] ['b', 'p'] will be merged to ['a', 'b', 'g', 'p'] The answer should be: [['a', 'b', 'g', 'p'], ['c', 'd', 'u'], ['e', 'f', 'k']] Anyone has a solution? Thanks, JD -- http://mail.python.org/mailman/listinfo

Hi, Thanks for the help, but the result is not quite right: [['a', 'b', 'g'], ['c', 'd', 'u'], ['b', 'p'], ['e', 'f', 'k']] the ['b', 'p'] is not merged. JD On Oct 17, 2:35 pm, Chris Rebert [EMAIL PROTECTED] wrote: (Disclaimer: completely untested) from collections import defaultdict

Apologies for essentially talking to myself out loud! I've switched back to pygresql. I think a lot of my problems were caused by not having installed postgresql-server-dev-8.2 which contains a lot of header files etc. I'm sure this was part of the problem with the psycopg modules aswell.
