When you import one module from another in Python, you're really doing two things: 1) Load the module if it's not already loaded 2) Create a reference to that module in the current module There's nothing like a hierarchical relationship here. > Adding them in the way you mention does not add them to globals. There isn't really such a thing as a "global" global in Python in the sense of (say) a C++ global variable. Globals are always scoped to the module they're in. The closest thing there is to this in Python is the list of loaded modules -- and even that can be manipulated, given that it's really just a dictionary contained within the "sys" module. If you've done the equivalent of poking "a = 1" into module "foo", you can access this value from __main__ by saying "from foo import a". -- Curt Hagenlocher [EMAIL PROTECTED] ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com

So, if I have a module and inside that module I have an import
statement. Does that imported module reside below the ScriptScope of
the module I created? The reason I ask is that I have a file that I
create a module from called __main__. I then add some variables to
that module __main__.SetVariable("name", value). I would think that I
need to access them by importing my original script and referencing
them that way; what I want to do is access them via the globals().
Adding them in the way you mention does not add them to globals.
Thanks,

What kind of reference do you have to the script from the hosting code? If you've got a ScriptScope for the module, you can just say PythonEngine.CurrentEngine.SetVariable(module, "varName", varValue) where module is the ScriptScope. -- Curt Hagenlocher [EMAIL PROTECTED] ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
[IronPython] Hosting and globals
I am trying to update my application to use the Hosting APIs from alpha 7, one thing that I can't seem to figure out is how to access "globals" to add stuff from my application to be used by the script. Any help would be appreciated. Thanks, slide ___ Users mailing list Users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
