Either one will probably suit your needs. For practical purposes, the
difference is one of interface - odeint has a more procedural
interface, while ode has a more object-oriented one. Underneath, both
use well-established fortran ODE integrators (odeint uses LSODA from
ODEPACK, and ode uses VODE). odeint may also have problems on a 64-bit
system, IIRC.

If you need a more sophisticated integrator (stopping based on the y
value, for example) look at the PyDSTool package.
