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

The shutils.copytre e() command[1] will do what you describe

Depending on your source, and if you want to make the dest
writeable (such as copying off a CD), you may also need to use
os.walk() [2] combined with os.chmod(filepa th, stat.S_IWRITE) [3]

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

copytreetosingl efolder('c:\\sr c','d:\\dest')

Please use a mailer/news-agent that preserves whitespace on the
beginning of the line, and make sure you don't use tabs but spaces to
indent.

Apart from that - why don't you use shutil.copytree ? Regarding the error
- are you allowed to copy, can you do it using the shell?

OP stated requirements were to move all the files into a single
folder. Copytree will preserve the directory structure from the source
side of the copy operation.

Python isn't going to let you get around operating system access
controls. Check the permissions on the source directories...
