Formatting inequalities display

When solving inequalities of the type $x^2-1>0$ I use the code solve(x^2-1<0,x) to obtain the answer [[x > -1, x < 1]].

Question 1: Is there a way to make Sage display this solution as -1<x<1?

Question 2: Is there an already implemented way to change the display of the inequality x>1 to 1<x?

In your case you can use your own function:

def show_result(sol):
    L = [s.rhs() for s in sol[0] ]
    print ' %s < %s < %s ' %(min(L),sol[0][0].variables()[0],max(L) )

show_result(solve(x^2-4<0,x))
