(Obsolete) The dircache module contains a function to get a list of files in
a directory. It’s an extension of the os.listdir
function in that it keeps a cache to avoid rereading a directory that
hasn’t 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
