SymPy: Limit symbol/variable to interval

Question

Using SymPy, is it possible to limit the possible values of a symbol/variable to a certain range? I now I can set some properties while defining symbols, like positive

Answer 1

You can specify the bounds as inequalities such as x >= lb and x <= ub, for example:

from sympy.solvers import solve
from sympy import Symbol
x = Symbol('x')
solve([x >= 0.5, x <= 3, x**2 - 1], x)

Here we search for a solution of equation x**2 == 1 such that x is in the interval [0.5, 3].
