Question

I have a Python file with as content:

import re
import urllib

class A(object):
    def __init__(self, x):
        self.x = x

    def getVal(self):
        return self.x

    def __str__(self):
        return "instance of A with value '%s'" % (self.getVal())

I also have a simple C# console project with the following code:

engine = Python.CreateEngine();

ScriptSource source = engine.CreateScriptSourceFromFile("test.py");
ScriptScope scope = engine.CreateScope();
ObjectOperations op = engine.Operations;

source.Execute(scope); // class object created

object klaz = scope.GetVariable("A"); // get the class object
object instance = op.Call(klaz, "blabla waarde"); // create the instance
object method = op.GetMember(instance, "getVal"); // get a method

string result = (string)op.Call(method); // call method and get result (9)
Console.WriteLine("Result: " + result); //output: 'Result: blabla waarde'

(I got this from this stackoverflow querstion and answer)
If I leave out the the import urllib statement in the Python file everything works fine. (meaning it finds the re module)
But as soon as i either add import urllib or import urllib2 I get the following exception:

ImportException was unhandled
No module named urllib

So somehow it can’t find the urllib. I checked the IronPython lib folder and both urllib and urllib 2 are definitely there.
The same exception gets thrown when I import urllib in the C# code. (engine.ImportModule("urllib");)

Any ideas?
I’d like to manage the imports in the python code and not in the C# code.
(So I’d like to avoid stuff like this: engine.ImportModule("urllib");)

Edit:
Some extra info on what I’m actually going to use this for (maybe someone has an alternative):
I will have a main C# application and the python scripts will be used as extensions or plugins for the main application.
I’m using Python so that I don’t need to compile any of the plugins.

I face the same problem. Following “Tom E’s” suggestion in the comments to fuzzyman’s reply I could successfully resolve the issue. The issue seems to be it is not able resolve the location of the urllib.py. We need to set it.
