Book Examples Distribution
This section briefly discusses the book’s example source code distribution, and covers example usage details.
The Book Examples Package
The
Examples\PP2E
CD directory is a Python module
package that contains source code files for all examples presented in
this book (and more). The PP2E
package in turn
contains nested module packages that partition the example files into
subdirectories by topic. You can either run files straight off the
CD, or copy the PP2E
directory onto your
machine’s hard drive (copying over allows you to change the
files, and lets Python store their compiled bytecode for faster
startups).
Either
way, the directory that contains the PP2E
root
must generally be listed on the Python module search path (normally,
the PYTHONPATH environment variable). This is the only entry that you
must add to the Python path, though; import statements in book
examples are always package import paths relative to the
PP2E
root directory unless the imported module
lives in the same directory as the importer.
Also in the examples package, you’ll find scripts for
converting example files’ line-feeds to and from Unix format
(they are in DOS format on the CD--see http://examples.oreilly.com/python2), making files writable (useful
after a drag-and-drop on Windows), and more. See the README files at
the top of the Examples
and
PP2E
directory trees for more details on package
tree usage and utilities.
