Continuous system simulation in Python

Nicholas,

Have you looked at Octave? It is not Python, but I believe it can talk
to Python.
Octave is comparable to Matlab for many things, including having ODE
solvers. I have successfully used it to model and simulate simple
systems. Complex system would be easy to model as well, provided that
you model your dynamic elements with (systems of) differential
equations.
