Adventures in Python, Part 1:

Attempt 1


MyPackage/init.py:
        MyGlobal = initialize()
client.py:
        from MyPackage import MyGlobal  # FAIL; MyGlobal isn't defined.

Attempt 2


MyPackage/init.py:
        MyGlobal = initialize()
        def getter():
            return MyGlobal
client.py:
        from MyPackage import getter
        MyGlobal = getter()
MyPackage/otherthing.py:
        MyGlobal.doSomething()  # FAIL: MyGlobal isn't global to the package

Attempt 3


MyPackage/globals.py:
        MyGlobal = None

MyPackage/init.py:
        from globals import MyGlobal
        MyGlobal = initialize()
        def getter():
            return MyGlobal
MyPackage/otherthing.py:
        from globals import MyGlobal

        MyGlobal.doSomething()  # FAIL; MyGlobal == None

Attempt 4


MyPackage/globals.py:
        MyGlobal = None

MyPackage/init.py:
        import globals
        globals.MyGlobal = initialize()
        def getter():
            return MyGlobal
MyPackage/otherthing.py:
        from globals import MyGlobal

        MyGlobal.doSomething()  # Success, finally

Oh well. It still beats EnterpriseVisualBeans.
