Introduction
Pro Django represents seven years of accumulated knowledge in Python and Django, designed to educate readers
who are already familiar with both topics and would like to take them further than they had previously done. You will
learn a wide range of advanced techniques available in both Python and Django, along with tips on how to use them
to achieve advanced functionality.
is book is designed to be both a narrative to be read from start to nish and a general reference to be searched
for specic information. Since you may not know what to look for or where to nd it yet, feel free to read through the
book rst, then keep it handy for refreshing your memory as necessary.
What This Book Is Not
ere are plenty of resources available for learning Python and Django, so this book does not strive to teach the basics.
For readers new to Python, I highly recommend Dive Into Python 3 by Mark Pilgrim (Apress, 2009). For learning
Django, I’d recommend e Denitive Guide to Django: Web Development Done Right by Adrian Holovaty and
Jacob Kaplan-Moss (Second Edition, Apress, 2009). Additionally, Practical Django Projects by James Bennett
(Second Edition, Apress, 2009) is an excellent resource for general application development.
Who This Book Is For
Because Pro Django doesn’t dwell on introductory details, readers will be expected to have experience with both
Python and Django. If you’re new to either subject, please consider one of the books mentioned in the previous
section before trying to tackle this book.
Even if you’ve only experimented on your own without launching a full site yet, a basic familiarity should be
sucient. You don’t need to be an expert to start reading Pro Django, but you might be by the time you nish.
Interpreting Code Samples
Pro Django uses a simple format, interleaving explanations of Python’s and Django’s available features with code that
demonstrates their use in the real world. ere are two types of code samples used, which dier in how they should be
executed.
Python’s interactive interpreter is a great way to test out small pieces of code and see how it works in a variety
of situations. Lines of code intended for use in that environment will always be prexed with three characters: three
greater-than signs (>>>) or three periods (. . .). Lines with greater-than signs are the outermost block of code, while
the period-prexed lines are indented at least one level. e three initial characters are also followed by a space. ese
rst four characters are not typed into the interactive interpreter directly; they simply mimic what the interpreter itself
looks like by reproducing its output.
