OT: Python

[AngleWyrm]

With Python,

How would I change a directory of filenames from whatever_stuff.txt to new_stuff.txt?

CKrename is a handy little program that does this and more... google it!

Personally, I'd use CK Rename for batch file renaming. But in a python script, you would need something like:

Code:

---

import os

import re



oldstring = 'whatever'

newstring = 'new'



name_match = re.compile(oldstring)



os.chdir('target')



print 'preop:'

print os.listdir('.')



for f in os.listdir('.'):

  os.rename(f, name_match.sub(newstring, f, count=1))



print 'postop:'

print os.listdir('.')

---

Make sure to replace 'target' with the directory containing the files.

Alternatively without much extraneous bits:

Code:

---

import os

import re



name_match = re.compile('whatever')



os.chdir('target')



for f in os.listdir('.'):

  os.rename(f, name_match.sub('new', f, count=1))

---
