Subject: [Python.NET] tuple not recognized as a type ?
Message-ID: <978977470905010850s49b9f54aqfe3366ef18fa7441@mail.gmail.com>

Hello,
I have been trying to use tuple as a generic type argument:
In [4]: from System.Collections.Generic import List
In [5]:
In [6]: x = List[int](range(4))
In [7]: x = List[tuple]([() for t in range(4)])
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

h:\python\testPyNet.py in <module>()
----> 1
      2
      3
      4
      5

TypeError: type(s) expected

I had a similar problem in a generic method of a non-generic class.

I have two questions:
* Is there a work around ?
* How do you debug python for .NET ?
  I tried to attach a Visual Studio 2005 debugger to the python process and
break in ClassObject.type_subscript but VS does not load the symbols.

Thanks for this project, I would love to use it.

If  you have your .net assembly put up a modal dialog (messagebox), you can attach to the process from DevStudio, set breakpoints, etc.

Hi Brett ? Generics only work with CLR types and primitive Python types that
have 
a direct CLR equivalent (string, int, etc.), so you really can?t do this
with tuples. Not 
sure what you were going for in the example, but generally you will want to
use 
CLR collection types when interacting with CLR objects and apis.

For debugging your best bet would be vstudio for looking at the integration
layer, 
but YMMV given all the transitions between managed code, native code,
generated 
code, etc.

hope this helps,

-Brian

Subject: [Python.NET] Python.Runtime as a reference in my C# project
Message-ID: <F7E6AEEFF2D9694DB7F92FD6A86774C9051CD04D@PDC-MAIL1.ubisoft.org>

Hello

 

I'm trying to develop a python console in WPF : to do it I have to execute a C# string as a python expression.

When I initialize the python engine (python 2.6), I get an exception (incorrect format). If I delete the python26.dll, it is asking for it, so it must be a version issue but I really have no clue to solve it.

It turns out that the "Console" project inside pythonnet solution has the same issue.

 

Does it work for you?

 

Thanks

Guillaume

Message-ID: <F7E6AEEFF2D9694DB7F92FD6A86774C9051CD01D@PDC-MAIL1.ubisoft.org>

Hi everybody !

We are looking forward for using python for .Net in our project.  I am
very impressed by the library that is working today on .Net 3.5 (WPF and
co) and python 2.6 virtually without any commit for the last couple of
years! J

Still, what do you think about python 3.0? Have you ever tried to be
compatible with it? Is there any big issue you have already imagine?

 

Thanks

Guillaume

Hi Guillaume ? the runtime is very sensitive to internal structural changes
in 
the CPython runtime, so I?m sure there would be some work involved. Some
things I can think of off the top of my head:

  - unicode changes / bytes type (this could be a giant pain)

  - int / long unification

  - need to support views and iterators

  - exception hierarchy changes

  - extension api changes

It?s probably enough work that it will take someone committed and invested
to make it happen...
