PYTHON solving the integral of a differential equation with odeint get error

I have a problem with the integration of this differential equation R*(dq/dt)+(q/C) = Visin(wt) i want to solve it to get q(t) but i don't get anything with odeint.

def f (R, w, C, Vi):
   return R*(dq/dt)+(q/C) = Vi*sin(w*t)
odeint(f,
