I'd like to spread the definition of a large multivariate symbolic
function across several input lines (because it will eventually end up
on a piece of paper - how quaint). Here is a simple example you can
drop on a command line, or put into a two-line cell in the notebook
without the triple dots, but physically on two lines.
T(r, t) = [r^2,
... t^2]
Preparser cannot handle the continuation:
File "<ipython console>", line 1
__tmp__=var("r,t"); T =
symbolic_expression([r**Integer(2),).function(r,t)
Workaround:
outputs = [r^2, t^2]
T(r, t) = outputs
But if you start with this, the symbolic variables are not declared
when you form the list - you lose some preparser magic. So it needs
to become:
r, t = var('r, t')
outputs = [r^2,
... t^2]
T(r, t) = outputs
Not intolerable for a huge example, but it would be nice to just have
a one-statement, multiple-continuation version possible.
Any better workarounds? Any hope the preparser could be extended to
handle this sort of thing?
