How should I check if I can create files in a directory?
I tried to simply check if the directory is writeable with this function:
def is_writable(name):
"""Return true if the file is writable from the current user
"""
return os.access(name, os.W_OK)
but that doesn't work at all on

Ok, doing os.environ['http_proxy']='' before importing urllib2 seems
to do the trick for that.

self is meaningless outside a class definition. You should refactor your

an instance and call the methods on that instance.

I see that there was previously a PEP to allow the with statement to skip the
enclosing block... this was shot down, and I'm trying to think of the most

Sure. But first can you show us some code that reads a pickled file
and prints the contents?

It is a bit non-normal. but I think this is a good use case as I want to

The book I'm reading about using Tkinter only does this when creating the

app.mainloop()
and of course the Application class has subclassed the tkinter.Frame class.
