more regexp

[hokiegal99]

I can replace all spaces in filenames and directory names with this bit
of code: (thanks to all who helped me get this!)

fspaces = re.compile('[ ]')

for root, dirs, files in os.walk('/test/dir'):
for file in files:
badchars = fspaces.findall(file) #find spaces
newfile = ''
for badchar in badchars:
newfile = file.replace(badchar,'%')
if newfile:
newpath = os.path.join(root,newfile)
oldpath = os.path.join(root,file)
os.rename(oldpath,newpath)

dspaces = re.compile('[ ]')

for root, dirs, files in os.walk('/test/dir'):
for dir in dirs:
badchars = dspaces.findall(dir) #find spaces
newdir = ''
for badchar in badchars:
newdir = dir.replace(badchar,'%')
if newdir:
newpath = os.path.join(root,newdir)
oldpath = os.path.join(root,dir)
os.rename(oldpath,newpath)

Now, I'd like to be able to search for the '%' character at the begining
and the ending of filenames and dirs and remove them entirely. Could
someone suggest a way to do this? Any tips are welcomed!

Sorry if I'm missing something since I'm jumping into this thread
late, but if all you want to do is replace spaces, why do you need
regexps? Can't you just use string.replace?

See also lstrip and rstrip to remove chars (default whitespace) from
the beginning or end of a string (strip does both beginning and end).
