Someone wanted to use the tools I wrote for the cardboard bookscanner on a non-windows platform… et voilà, the same functionality in Python (2.7.3):

A python rendition of RenameAll.exe (http://www.mattikariluoma.com/files/RenameAll.exe)
from the Cardboard Bookscanner project, Jan 2010.

This script loads a directory of images, then renames them all such
that the first half and the second half are intersperesed. The input
directory is expected to contain 2n or 2n+1 images, where the first n
images are of the right-hand side of a book, and the last n are the
left-hand side of the book.
"""
import os, sys, glob
import cv
images_filename = []
images_filename = glob.glob1(sys.argv[1], "*.[j,J][p,P,pe,PE][g,G]")
images_filename.sort()
NUM_PIC = len(images_filename)
n = 0
for filename in images_filename:
image = cv.LoadImage(sys.argv[1]+"/"+filename)
if (n < NUM_PIC / 2):
#sprintf(temp, "%06d-a.jpg", n+1)
cv.SaveImage(sys.argv[1]+"/%06d-a.jpg" % (n+1), image)
else:
#sprintf(temp, "%06d-b.jpg", n+1-NUM_PIC/2)
cv.SaveImage(sys.argv[1]+"/%06d-b.jpg" % (n+1-NUM_PIC/2), image)
n += 1
Truth be told, I only wrote the tools so windows users could play along too; I imagined non-windows users would write some shell one-liners.
