OpenMaple Application Program Interface (API) for Python
OpenMaple for Python provides an interface between the Maple evaluation engine and a Python program. This is implemented using Python classes and standard interfaces.
Overview
maple Package
namespace Subpackage
Classes
To use the Maple API for Python, start by importing the library maplesoft.maple. This implicitly launches a Maple session.
import maplesoft.maple
The maple package has the following commands:
range
symbol
symbols
To access Maple variables and predefined functions and commands, you can use the symbol or symbols function or import the maple.namespace interface:
The symbol function returns an Expression object.
The symbols function returns a tuple of Expression objects.
The namespace subpackage offers general access to any Maple name or function.
The range function returns an Expression object corresponding to a Maple range.
The maple.namespace subpackage allows any Maple name or function to be accessed with a simple prefix. This prefix is arbitrary, but for consistency in these examples we will assume the subpackage was assigned the name msymbol after being imported with the following command.
import maplesoft.maple.namespace as msymbol
Global names or commands may be referenced as msymbol.sin, msymbol.solve, etc.
Commands in Maple packages or subpackages may be referenced using the chosen prefix and replacing instances of the Maple member selection operator (:-) in the Maple qualified name with a period (.). For example, LinearAlgebra:-Determinant would become msymbol.LinearAlgebra.Determinant.
Every OpenMaple object created in a Python session is an Expression object.
Depending on the type of the underlying Maple expression, the object may also be an instance of a subclass of Expression , such as ComplexNumeric or List .

The Expression class is the parent class of all the classes that represent Maple objects. Its member functions provide access to all the basic functions that can be performed on a Maple expression.
__abs__
__add__
__call__
__ceil__
__eq__
__floor__
__floordiv__
__ge__
__getitem__
__gt__
__hash__
__le__
__len__
__lt__
__mul__
__ne__
__neg__
__pow__
__radd__
__rfloordiv__
__rmod__
__rmul__
__round__
__rpow__
__rsub__
__rtruediv__
__sub__
__truediv__
__trunc__
eval
The ComplexNumeric class represents complex numbers. Conceptually, a ComplexNumeric object contains two RealNumeric objects: its real part and its imaginary part.
Inherits from Expression.
conjugate
imag
real
The RealNumeric class represents numeric literals. Note that Maple integers and fractions appearing in output from OpenMaple computations are represented as Python integers and Fractions.fraction objects, so this class is effectively only used for floating-point numbers.
Inherits from ComplexNumeric.
The Name class represents a Maple symbol. This includes both global symbols and names defined in Maple packages.
__getattr__
assign
The Indexable class is the parent class of all the classes that represent Maple collections. Its member functions provide access to the basic functions that can be performed on a collection, such as querying its size and testing for membership.
__contains__
__iter__
The ExpressionSequence class represents a Maple expression sequence .
Inherits from Indexable.
__reversed__
index
The List class represents a Maple list .
The RTable class represents an rtable (rectangular table), a Maple data structure for storing homogenous data of arbitrary dimension.
__bytes__
The Set class represents a Maple set .
__`and`__
__`or`__
__`xor`__
isdisjoint
The Table class represents a table. Data can be inserted and removed from the table and a table can be searched for a particular element.
