Comment #1 on issue 1838 by smichr: Add support for [0]*S(5), etc.
http://code.google.com/p/sympy/issues/detail?id=1838
This works in python from the left or right.
2*[1,2,3]
[1, 2, 3, 1, 2, 3]
[1,2,3]*2
[1, 2, 3, 1, 2, 3]
2*'o'
'oo'
For sympy, however, we might want to override that behavior and do
something like
vector multiplication which, in the case of noncommutives, could be done
from the
left or the right. So it would be possible to make
S(3)*[1,2,3] give [3, 6, 9]
and for noncommutative x,
[a, b, c]*x give [a*x, b*x, c*x]
or x*[a, b, c] give [x*a, x*b, x*c]
This could be extended to Eq and Matrix classes, too.
