Its a wonderful read. Will really unleash the pythonista inside of all us!
If you really want to go deeper, I suggest these as well:

Those shortened links take you to amazon (not affiliated in any way, FYI, just though the length of the URLs was obnoxious)
Those are the definitive python programming books I came up with anyway.
While we are at, I have to say once I learned to really code Pythonically I find that I can apply the PEP8 standards to almost any language. Admittedly, I, like John Siracusa, am a top level language debutante and don't live in C or C++ production code (I sometimes use objc but swift is...easier :). I remember learning C, and thanks to arduino I certainly using some varient of C/c++ there more heavily, but my coding style follows more or less the pythonic standard (with PEP8 being the backbone of that).
food for thought, people of hacker news!
