dynimac code with lambda function creation

[Justin Delegard]

So I am trying to pass an object's method call to a function that 
requires a function pointer.  I figured an easy way to do it would be to 
create a lambda function that calls the correct method, but this is 
proving more difficult than I imagined.

Here is the function I'm using:

def objectMethodCallerFunctionCreator(testerObj, method):
    exec("y=lambda x: testerObj."+method+"(x)")
    return y


Where testerObj is an instance of an object, and method is a string 
representing the method to call.  The problem is, when I actually run 
the function created (y in this case), it tells me it can't find the 
symbol testerObj in the global scope.  I have successfully created 
similar functions, except without using the exec() call. e.g.

def functionCreator(a, b, c):
    return lambda d: myFunc(a, b, c, d)

and it doesn't complain about the variables a, b, or c when being run.  
I am assuming this is happening because of the exec() call, but I don't 
see another way of calling a variable method on an object.  Is there 
some other way to do this that I'm missing?  I tried passing in 'method' 
as a function pointer (to the method of the object), but that didn't 
work either.

Thanks,
Justin
