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:

<font class="small">Code:</font><hr /><pre>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('.')</pre><hr />

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

Alternatively without much extraneous bits:

<font class="small">Code:</font><hr /><pre>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))</pre><hr />
