[SciPy-user] Solving "difference" equations

Dear Scipy users,
I would like to know whether SciPy has a facility allowing one to
solve discrete-time difference equations. For example, equations like
the following:

y[n] = y[n - 1] + x[n], n is an integer.

I tried using odeint, but it solves it as a continuous time equation
(or so I think...). Setting hmax to 1.0 also doesn't help.

What is the right way?

Thanks.

Kumar
