Hi,
I'd like to pack some modules in a package. Each module contains a single
class, which forces me to
from Pythonsite.Show import Page
page = Page()
...
class Page(Site.DB): #class DB from module Site in package Pythonsite
...
Is there a way to define a default class for a module which would me allow to
from Pythonsite import Show
page = Show() #page as an instance of default class in Show
class Page(Site): #Page as a subclass of default class in Site
I don't know of any way to do exactly what you ask. However you can use the
__init__.py module of the package to promote classes to package level
visibility.
For example suppose you have
mypackage/
__init__.py - empty
myclass.py - defines MyClass
myotherclass.py - defines MyOtherClass
To use this you would for example
from mypackage.myclass import MyClass
mc = MyClass()
But if you put these lines in __init__.py:
from mypackage.myclass import MyClass
from mypackage.myotherclassimport MyOtherClass
this brings the class names into the module namespace. Now you can say
from mypackage import MyClass
mc = MyClass()
I suppose you could do your example by including this line in __init__.py:
from Pythonsite import Show
Show = Show.Page
Then clients that say
from Pythonsite import Show
will actually get Show.Page which is what Pythonsite.Show is now bound to, but
that seems unneccesarily twisted and obscure to me.
