The book has python 2.x code. If the modules in the book use the Natural
Language Toolkit (nltk), then I believe you are currently stuck with
using 2.7.
If it does not, and you want to run with 3.3 or 3.4, then use 2to3 to do
most to all of the conversion for you.
C:\Programs\Python34>python Tools/scripts/2to3.py -h
Usage: 2to3 [options] file|dir ...
Options:
-h, --help show this help message and exit
-d, --doctests_only Fix up doctests only
-f FIX, --fix=FIX Each FIX specifies a transformation; default: all
-j PROCESSES, --processes=PROCESSES
Run 2to3 concurrently
-x NOFIX, --nofix=NOFIX
Prevent a transformation from being run
-l, --list-fixes List available transformations
-p, --print-function Modify the grammar so that print() is a function
-v, --verbose More verbose logging
--no-diffs Don't show diffs of the refactoring
-w, --write Write back modified files
-n, --nobackups Don't write backups for modified files
-o OUTPUT_DIR, --output-dir=OUTPUT_DIR
Put output files in this directory instead of
overwriting the input files. Requires -n.
-W, --write-unchanged-files
Also write files even if no changes were required
(useful with --output-dir); implies -w.
--add-suffix=ADD_SUFFIX
Append this string to all output filenames.
Requires
-n if non-empty. ex: --add-suffix='3' will
generate
.py3 files.
This is the user interface for lib2to3.
