pass data structure to PyShell

wxPython Users

Hello,
My application generates a data structure with some methods. After that, the application launchs a PyShell. I would like to enable the user to use that data structure, or its methods directly from the shell. How is this possible?
Thanks for any hints.

Put a reference to the data in a dictionary and then pass the dict to PyShell as the locals parameter. Whatever is in that dict will be added to the local varaiables visible in the shell.

Robin, thanks a lot for your response. But I am not quite sure how to implement what you suggest by:

Put a reference to the data in a dictionary and then pass the dict to PyShell as the locals parameter. Whatever is in that dict will be added to the local varaiables visible in the shell.

Imagine I have a class CDrive

class CDrive:
     def __init__(self):
  # DO SOMETHING

     def SetValue(self,tag,value):
  # DO SOMETHING
         pass

class CCommandShell:
     def __init__(self, drive): # we pass the actual drive
         self.frame = wxFrame(None, -1, "Drive Manager Command Shell")
         self.frame.SetSize((800, 400))
         win = py.shell.Shell(self.frame, -1,
    introText="Drive Manager interactive command shell\n\n")
         self.frame.Show()

then I want to do something like

  drive = Cdrive()
  shell = CCommandShell(drive)

which will open a frame containing the shell, which will allow the user
to access the methods like.

I did not find a documentation of PyShell which explains all the parameters being passed. Where should I look?

Thanks a lot,
peter

In wxPython/py/shell.py
