if n == k:

Hi,
Current software development methods make things way more complex than
they need to be. I am trying to get an idea for how simple things can

Hi,
I'm trying to figure out where 'simpler' stops and 'too simplistic'
begins. That's what I call 'absolute simplicity'. It is a necessity in

There is another one.
Once object passes through singletonizator
there wont be any other object than first one.
Then object constructor can freely be used in every place
of code.

As Mark said, we need a bit of context in your emails. This on its own
carries no information.

Report what, you keep sending us one liners with no context?

This is from the book 'dive into python'. I am trying to define jeez as being
an instance of FileInfo.

self.data = {}

What happened? I'm not seeing any exception information. I do see code
that doesn't quite make sense.

Those two classes are from this code here(pasted below). Quite frankly, I don't

Also, UserDict is a built in module. I just typed it out so as to give
reference or any clue as to why I cant instantiate jeez.

Recommendation for next time: Don't type it out, copy and paste it.
Show the actual code you ran, and the actual error m

I always thought sticking an object in a module is the simplest form of
singleton.
