Yes, you can, but consider passing the object as an argument. Global  
objects aren't necesarily evil, anyway I don't have enough information to  
make an opinion.

If you insist on use the global object, there is another question.  
__init__.py defines the package namespace, and is the public interfase to  
it, I would not put an object there that is not supposed to be part of the  
package public interfase. You can instantiate the object in any other  
module, and import such module from both file1 and file2.
