By definition, rc4's output is predictable if you know the seed. It is
just a PRNG -- in my opinion, though, a much better one than random()
although not quite up to strong cryptographic use.

I'm a big fan of RC4 for things like monte carlo work and such -- much
better results than Linear Congruential produces. I wouldn't generate
RSA keys using RC4 but that's a totally different story.
