For some recent computations, I devolved some initial calculus to the Maxima sub-system, and I've ended up with a list eqs of Maxima expressions. I want to transfer this list out of Maxima. This works:
sage: eqs2 = [repr(xx) for xx in eqs]
but gives me strings, which are not useful. And this:
sage: eqs2 = [sage_eval(repr(xx)) for xx in eqs]
returns the error message
NameError: name 'a43' is not defined
which is strange, as it is defined as a variable:
sage: a43
a43
I could create a list of local variables:
vars = {'a21':a21,'a31':a31}
and so on, and use
sage_eval(xx,vars)
but as there are 20 more variables, this would be tedious.
Is there a better way?
