About output "Julia types" from Python functions.

[martinmestre]

Hi!
I would like to know if it is correct that all the outputs of python functions have julia type Py.
Is it possible to specify more the type in such a way to use multiple dispatch depending on the python type?
If not, which is the correct way to assign a specific julia type instead of Py?
For example, I am referring to this python class.
Thank you.

Yes, PythonCall outputs Py from most functions that return some sort of Python object. Hence multiple dispatch on the Python type is not directly possible. For specific use-cases you can hack it yourself with something like:

foo(x::Py) = foo(x, Val(Symbol(x.__class__.__module__, ".", x.__class__.__name__)))
foo(x::Py, ::Val{Symbol("foo.bar")}) = ...
foo(x::Py, ::Val{Symbol("foo.baz")}) = ...
