Hi,

This is a nice library. Thanks a lot for this.

1) I was wondering if it is possible to perform certain sympy
operations, (like substitution, differentiation etc.) and then convert
the resulting expression into a pure python function, which could then
be used for map, reduce, filter etc. in python. Or for any other
purpose really.

2) Can one generate lagrangian equations of motion, if a lagrangian is
specified? Isn't that supposed to require something like a  functional
derivative? I don't care for the optimizations, or simplifications at
this time. I just want a bunch of ODE's I can plug into a solver.

Thanks,
