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))
