◆ __getitem__()

__getitem__ ( self,

Return the Z3 expression `self[arg]`.

>>> a = Array('a', IntSort(), BoolSort())
>>> i = Int('i')
>>> a[i]
a[i]
>>> a[i].sexpr()
'(select a i)'

4678
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 ...

◆ domain()

domain ( self)
Shorthand for `self.sort().domain()`.

Shorthand for self.sort().domain_n(i)`.

Definition at line 4650 of file z3py.py.

◆ sort()

sort ( self)
Return the array sort of the array expression `self`.

>>> a = Array('a', IntSort(), BoolSort())
>>> a.sort()
Array(Int, Bool)

Reimplemented from ExprRef.
