EmbedPy question, function in python that returns more than one value.
Python code : fig, axes = plt.subplots(ncols=2, figsize=(24, 8), dpi=100)
q code :
plt:.p.import[`matplotlib;`:pyplot]
plt[`:subplots;<;pykwargs `ncols`figsize`dpi!(2;24 8;100)] returns (foreign;foreign) – corresponding to (fig, axes) in python. How do I access each value of the returned list of (foreign;foreign), inside q?Thanks,
Kumar

Hi Kumar,
To index into a python objext you can use the syntax of a backtick character “`” to convert to q. E.g.
variable`If you have a list of variable you want to index into you could alternatively write
{x ` } each list_of_python_variables
or
list_of_python_variables@:`Depending on which syntax you prefer.
Cheers,
Sam

You can use .p.wrap https://code.kx.com/q/ml/embedpy/userguide/#embedpy-objects_1
Small example giving each subplot a title:
plt:.p.import[`matplotlib;`:pyplot] plts:plt[`:subplots;<;pykwargs `ncols`figsize`dpi!(2;24 8;100)] .p.wrap[plts[1;0]][`:set_title]"Plot1"; .p.wrap[plts[1;1]][`:set_title]"Plot2"; plt[`:show][];
