[Tutor] rename files

[Christopher Spears]

I'm trying to write a script that will rename files. 
The files are in this format: 

replace_dashes_stuff03

I want to rename the files to

replace.dashes.STF.v03

Here is what I have so far:

#!/usr/bin/python

import os,sys

oldFile = sys.argv[1]

if oldFile.find('_') != -1:
	print "Found dashes!"
	newFile_without_dashes = oldFile.replace('_','.')
	print newFile_without_dashes
	#os.rename(oldFile,newFile)
else:
	print "No dashes!"
	
if newFile_without_dashes.find('stuff') != -1:
	print "Found db!"
	newFile_without_db =
newFile_without_dashes.replace('stuff','STF')
	print newFile_without_db
	#os.rename(oldFile,newFile_without_db)
	 
Here is the result:

io at io-station-1 ./bin 125> replace_dashes.py
replace_dashes_stuff03
Found dashes!
replace.dashes.stuff03
Found db!
replace.dashes.STF03

Is there a more elegant way to do this?  I haven't
figure out how to convert stuff03 to STF.v03.

THanks!
