◆ __getitem__()

def __getitem__ (   self,

>>> a[i].sexpr()
'(select a i)'

Z3_mk_select
Z3_ast Z3_API Z3_mk_select(Z3_context c, Z3_ast a, Z3_ast i)
Array read. The argument a is the array and i is the index of the array that gets read.

expr range(expr const &lo, expr const &hi)
Definition: z3++.h:3488
Z3_mk_array_default
Z3_ast Z3_API Z3_mk_array_default(Z3_context c, Z3_ast array)
Access the array default value. Produces the default range value, for arrays that can be represented ...
Z3_get_sort
Z3_sort Z3_API Z3_get_sort(Z3_context c, Z3_ast a)
Return the sort of an AST node.
