This is going out of my field of knowledge but I reckon using the same variable name for nested loop is not a real issue with for loops (in the sense that it will perform the number of iteration you'd expect). You can reuse underscore everywhere and it should work : len([0 for _ in range(10) for _ in range(10)]) == 100. I am not sure what the usage is in that case.

Is there a reason for using range(0,10) instead of range(10)?

And self.values = {n:True for n in range(0,10)} becomes: self.values = dict.fromkeys(range(0,10), True). You can also drop the [ and ] in the join call and avoid building a useless list.
