def eq | ( | self, | |
other | |||
) |
Return `True` if `self` and `other` are structurally identical. >>> x = Int('x') >>> n1 = x + 1 >>> n2 = 1 + x >>> n1.eq(n2) False >>> n1 = simplify(n1) >>> n2 = simplify(n2) >>> n1.eq(n2) True

def get_id | ( | self | ) |
Return unique identifier for object. It can be used for hash-tables and maps.
Definition at line 300 of file z3py.py.
def hash | ( | self | ) |
Return a hashcode for the `self`. >>> n1 = simplify(Int('x') + 1) >>> n2 = simplify(2 + Int('x') - 1) >>> n1.hash() == n2.hash() True
Definition at line 341 of file z3py.py.
def sexpr | ( | self | ) |
Return an string representing the AST node in s-expression notation. >>> x = Int('x') >>> ((x + 1)*x).sexpr() '(* (+ x 1) x)'

def translate | ( | self, | |
target | |||
) |
Translate `self` to the context `target`. That is, return a copy of `self` in the context `target`. >>> c1 = Context() >>> c2 = Context() >>> x = Int('x', c1) >>> y = Int('y', c2) >>> # Nodes in different contexts can't be mixed. >>> # However, we can translate nodes from one context to another. >>> x.translate(c2) + y x + y
