copying files through Python

[Lalit]

I am new to python. Infact started yesterday and feeling out of place.
I need to write a program which would transfer files under one folder
structure (there are sub folders) to single folder. Can anyone give me
some idea like which library files or commands would be suitable for
this file transfer task. I am sure its matter of few commands. It
would be even more great if I could get some sample code with
instructions

Thanks

NameError: global name 'Response' is not defined

[Lalit]

Hi

I am very new to web development.  I started with Pylons. I am using
http://www.rexx.com/~dkuhlman/pylons_quick_site.html as reference to
create a sample web page using pylons.

I got stuck up at step 4.3 i.e when modifying controller to "return
Response('firstapp default')"

I am getting error of : global name
'Response' is not defined

It seems I am missing some package. I am not really sure. I installed
python 2.5 and through easy_install imported pakages (pylons).

Any clues would be appreciated

Thanks
Lalit

Re: copying files through Python

Hi this is the code which I wrote till now. It is giving permission 
denied error for sub folders of source directory. Does anyone have any 
idea what is going wrong

import os
import shutil
def copytreetosinglefolder(src, dst):
names = os.listdir(src)
if (os.path.isdir(dst)==False):
os.mkdir(dst)
for name in names:
srcname = os.path.join(src, name)
try:
shutil.copy2(srcname, dst)
except (IOError, os.error), why:
print "Can't copy %s to %s: %s" % (`srcname`, `dst`, str(why))

copytreetosinglefolder('c:\\src','d:\\dest')
