WebSymPy is also able to solve boolean equations, that is, to decide if a certain boolean expression is satisfi‐ able or not. For this, we use the function satisfiable: In [13]: satisfiable(x & y) Out[13]: {x: True, y: True} This tells us that (x & y) is True whenever x and y are both True. If an expression cannot be true, i.e. no
