datetime - simple renaming of file inside script keeping prefix -

i know there other questions renaming, have looked @ bunch, code won't work. have seen os python definitions.

basically code below part of larger script in gis running. have created geodatabase called permits.gdb , run necessary processing on data, want rename time stamp on backup purposes.

i getting errors file can't found... created in c:\test\permits.gdb know exists.... have seen several path examples ", ', /, , \, none seem work. path problem?

import time import os  dir_path = os.path.normpath('c:/test') dir = os.listdir(dir_path) = time.strftime('%h%m%a%d%m%y')  filename in dir:     old_name = "permits.gdb"     new_name = "baqp_permits_"+ +".gdb"     os.rename(old_name, new_name) 

update: thank guys help! got work still throws error can't find specified file though , renames it. saving in location want , have combined rest of script (so file paths different now) here new code:

dir_path = os.path.normpath('l:\gis_admin\sde_update_backup\baqp_permits') dir = os.listdir(dir_path) = time.strftime('%h%m%a%d%m%y')  filename in dir:     old_name = dir_path + "\baqp_permits.gdb"     new_name = dir_path + "\baqp_permits_"+ +".gdb"     os.rename(old_name, new_name) 

and error:

traceback (most recent call last): file "c:\ndepgis\scripts\baqp_permits_aris_daily", line 28, in <module> os.rename(old_name, new_name) windowserror: [error 2] system cannot find file specified  

try this:

import time import os  dir_path = os.path.normpath('c:/test') dir = os.listdir(dir_path) = time.strftime('%h%m%a%d%m%y')  filename in dir:     old_name = dir_path + "/permits.gdb"     new_name = dir_path + "/baqp_permits_"+ +".gdb"     print "filename", filename     print "old:", old_name     print "new:", new_name     os.rename(old_name, new_name) 

i don't think filename includes full path.
