Hi all, Just having started with python, I feel that simple array operations '*' and '+' don't do multiplication/addition but instead extend/join an array:
a=[1,2,3] >>> b=[4,5,6] >>> a+b [1, 2, 3, 4, 5, 6] instead of what I would have expected: [5,7,9] or >>> 2*a [1, 2, 3, 1, 2, 3] Well it is consistent to strings but tolerating string-operations to be special is ok to me as "a" + "b" -> 'ab' :) Why not make it another function like a.stretch() or a.expand() and a.extend() is there doing the same anyway and is more readable... Putting this in a larger view: Ufuncs are very reasonable sin(a), etc ... all that won't work because of that '+','*' syntax. Ok I can use numarray for that, but seeing its PEP and a possible inclusion into python at some point that inconsistency is giving me quite some headache... Will that change in the future ? Or is this 100*[0] syntax put into stone for all ages ? Best, Soeren. PS: As I am very new to python please forgive/correct me! -- http://mail.python.org/mailman/listinfo/python-list
