I made a utility library for downloading Wikimedia Data Dumps for analysis
I created a small utility library that exposes the directory structure of Wikimedia’s data dump site (and its mirrors).

It includes a method to easily download and decompress data dumps using Python’s built in libraries - this proved to be an especially difficult problem because the data dumps are sometimes several times larger than the system’s memory.
