The statcache module, shown in Example 14-15, contains a function that returns information about files.
It’s an extension of the os.stat function in
that it keeps a cache with recently collected information.
Example 14-15. Using the statcache Module
File: statcache-example-1.py
import statcache
import os, stat, time
now = time.time()
for i in range(1000):
st = os.stat("samples/sample.txt")
print "os.stat", "=>", time.time() - now
now = time.time()
for i in range(1000):
st = statcache.stat("samples/sample.txt")
print "statcache.stat", "=>", time.time() - now
print "mode", "=>", oct(stat.S_IMODE(st[stat.ST_MODE]))
print "size", "=>", st[stat.ST_SIZE]
print "last modified", "=>", time.ctime(st[stat.ST_MTIME])
