The dircache Module

(Obsolete) The dircache module contains a function to get a list of files in a directory. Its an extension of the os.listdir function in that it keeps a cache to avoid rereading a directory that hasn been modified. Example 14-17 demonstrates this.

Example 14-17. Using the dircache Module

File: dircache-example-1.py import dircache import os, time # # test cached version t0 = time.clock() for i in range(100): dircache.listdir(os.sep) print "cached", time.clock() - t0 # # test standard version t0 = time.clock() for i in range(100): os.listdir(os.sep) print "standard", time.clock() - t0 cached 0.0664509964968 standard 0.5560845807
