Question

how is this solution I am using now:

I have a 1MB .dbf file in the same directory of all my .py modules. In main.py I have

import tools

In tool.py code is :

the_list_that_never_changes = loadDbf(file).variables['CNTYIDFP'].

So the_list_that_never_changes is only loaded once and is always in memory ready to be used…correct?

Answer 1

Static files are stored apart from application files. If you need to load data.pkl from main.py, then don’t mark it as a static file and it will be accessible by main.py like any other application file.

Reference: Application Configuration’s Handlers For Static Files.

Alternative: Why not define the information stored in data.pkl as a global variable in your Python source? Then you don’t have to go through the trouble of reading a file and deserializing its pickled contents, and it will be a bit faster too. This will also make it easy to take advantage of app caching – your data will be loaded once, and then cached for use by subsequent requests.
