How can I make as "perfect" a subclass of dict as possible? The end goal is to have a simple dict in which the keys are lowercase. It would seem that should be some tiny set of primitives I can override to make this work, but all my research and attempts have made it seem like this isn't the case: If I override __getitem__/__setitem__...
I thought import sys sys.path.append("/home/me/mydir") is appending a dir to my pythonpath if I print sys.path my dir is in there. Then I open a new command and it is not there anymore. But somehow Python cant import modules I saved in that dir. What Am I doing wrong? I read .profile or .bash_profile will do the trick. Do I hav...

This is the settings.py file for python. I set mysql up via macports (mysql5 & mysqldb) The problem is that I am unsure if I have settings.py configuration correct before I sync the db. Should the PORT be left blank? I believe it should. I know on my Mamp install I have it set to 3306. Thanks.... DATABASES = { 'default': { '...
Ultimately, my goal is to extend Django's ModelAdmin to provide field-level permissions—that is, given properties of the request object and values of the fields of the object being edited, I would like to control whether or not the fields/inlines are visible to the user. I ultimately accomplished this by adding a can_view_field() method ...
def CreateDirectory(pathName): if not os.access(pathName, os.F_OK): os.makedirs(pathName) versus: def CreateDirectory(pathName): if not os.path.exists(pathName): os.makedirs(pathName) I understand that os.access is a bit more flexible since you can check for RWE attributes as well as path existence, but is th...

I am primarily a PHP developer, and I have been browsing the source code of a few open-source applications recently(Mozilla Bespin in particular), to find that some of them use a Python "back-end." I was just wondering what the purpose of this back-end is. I am assuming it is the same thing as the model in an MVC framework and is used ...
