selecting a class in execution time

[Brian Quinlan]

I'd be nice to know the why of this to suggest the best idiom.

> Object x = Class.forName( "mypackage.TheClass" ).newInstace();

x = getattr(__import__("mypackage"), "TheClass")()

The last set of parens is the argument list for TheClass' constructor.

If you know the name of the package at compile time then:

import mypackage
x = getattr(mypackage, "TheClass")()

Cheers,
Brian
