Passing parameterized function handle in Python

If you have:

def my_ode(K, tau, y, u):
    return K*u/tau - y/tau

you could define something like:

def make_ode_helper(k, tau): 
    return lambda (y, u): my_ode(K, tau, y, u)

and should be able to initialize MyThing with:

mt = new MyThing(make_ode_helper(k, tau), y0)

then you could call this helper with only y and u parameters:

someresult = ode_helper(y, u)
