What's the best way to pull out a common coefficient not depending on a given variable from an expression? I know there are a lot of functions that do things like this, but I never know which one to use. I want something like (all with respect to x):
3*x -> (3, x) 3*x + x**3 -> (1, 3*x + x**3) y*x + y*x**2 -> (y, x + x**2) My motivation is to pull out a common constant for integrate(). Currently it splits the integral using Add.make_args and then pulls out the constant for each term using as_independent, but I want to remove the splitting of Add args.
