The call type(x, python) checks to see if x is of type python. It returns true if x is of type python, and false otherwise.

An object is of type python if it is a reference to an object from a Python session running alongside the current Maple session.

Such objects may be created with commands from the Python package such as EvalFunction, EvalMember, EvalString, or GetVariable.

The convert/python function can convert expressions in Maple into type python expressions which reference equivalent Python expressions.

The convert/maple function can convert objects of type python to equivalent Maple expressions. Additionally, the following convert routines can also handle objects of type python:

type/foreign

$s≔\mathrm{Python}:-\mathrm{EvalString}\left(''set([3,5,7])''\right)$

$\mathrm{type}\left(s\,\mathrm{python}\right)$

$\mathrm{true}$

$L≔\mathrm{Python}:-\mathrm{EvalString}\left(''[1,3,5,5,8]''\right)$

$L≔\left[1\,3\,5\,5\,8\right]$

$\mathrm{type}\left(L\,\mathrm{python}\right)$

$\mathrm{false}$

$L≔\mathrm{Python}:-\mathrm{EvalString}\left(''[1,3,5,5,8]''\,\mathrm{output}=\mathrm{python}\right)$

$\mathrm{type}\left(L\,\mathrm{python}\right)$

$\mathrm{true}$

$M≔\mathrm{Matrix}\left(\left[\left[0.0357116785741896\,0.959492426392903\right]\,\left[0.655740699156587\,0.792207329559554\right]\right]\,\mathrm{datatype}=\mathrm{float}\left[8\right]\right)$

$M≔\left[\begin{array}{cc}0.0357116785741896& 0.959492426392903\\ 0.655740699156587& 0.792207329559554\end{array}\right]$

$\mathrm{type}\left(M\,\mathrm{python}\right)$

$\mathrm{false}$

$\mathrm{PM}≔\mathrm{convert}\left(M\,\mathrm{python}\right)$

$\mathrm{type}\left(\mathrm{PM}\,\mathrm{python}\right)$

$\mathrm{true}$

The type/python command was introduced in Maple 2020.
