How to query seed used by random.random()?

Is there any way to find out what seed Python used to seed its random number generator?

I know I can specify my own seed, but I'm quite happy with Python managing it. I want to know what seed it used, so that if I like the results I'm getting in a particular run, I could reproduce that run later. If I had the seed that was used then I could.

If the answer is I can't, then what's the best way to generate a seed myself? I want them to always be different from run to run - I just want to know what was used.
