import os, sys
# 显示文件的 stat 信息
stinfo = os.stat('a2.py')
print stinfo
# 使用 os.stat 来接收文件的访问和修改时间
print "a2.py 的访问时间: %s" %stinfo.st_atime
print "a2.py 的修改时间: %s" %stinfo.st_mtime
# 修改访问和修改时间
os.utime("a2.py",(1330712280, 1330712292))
print "done!!"
The above program output is:
posix.stat_result(st_mode=33188, st_ino=3940649674337682L, st_dev=277923425L, st _nlink=1, st_uid=400, st_gid=401, st_size=335L, st_atime=1330498070, st_mtime=13 30498074, st_ctime=1330498065) a2.py 的访问时间: 1330498070 a2.py 的修改时间: 1330498074 done!!
