Even though you deleted the module locally, it's still referenced in
the sys.modules cache (as well as in any other place where it might
have been imported). That's the place you need to delete it from if
you really want to re-execute it.

>>> import myModule
>>> myModule.myInt
1
>>> myModule.myInt = 2
>>> myModule.myInt
2
>>> import sys
>>> del sys.modules['myModule']
>>> import myModule
>>> myModule.myInt
1
