My personal library collecting some useful snippets.
Project description
About
This is my personal collection of snippets that I use in multiple projects. Each one feels a bit to small to merit it’s own library.
So what does it include?
memoize decorator (caching)
a storage class wrapping a dict.
unittest assert functions.
Functions for handling large JSON documents.
list_dir(path) –> (dirnames, filenames)
PID file locking
A synchronization decorator
