how to copy directory with all file from c:\\xxx\yyy to c:\\zzz\ in python

I've been trying to use "copytree(src,dst)", however I couldn't since the destination folder should exists at all.Here you can see the small piece of code I wrote:

def copy_dir(src,dest):
    import shutil
    shutil.copytree(src,dest)

copy_dir('C:/crap/chrome/','C:/test/')

and this is the error I m getting as I expected...

Traceback (most recent call last):
File "C:\Documents and Settings\Administrator\workspace\MMS-Auto\copy.py", line 5, in        <module>
copy_dir('C:/crap/chrome/','C:/test/')   
File "C:\Documents and Settings\Administrator\workspace\MMS-Auto\copy.py", line 3, in copy_dir
shutil.copytree(src,dest)
File "C:\Python27\lib\shutil.py", line 174, in copytree
os.makedirs(dst)
File "C:\Python27\lib\os.py", line 157, in makedirs
mkdir(name, mode)
WindowsError: [Error 183] Cannot create a file when that file already exists:    'C:/test/'

Here is my question is there a way I could achieve the same result without creating my own copytree function?

Thank you in advance.

Solution

Look at errno for possible errors. You can use .copytree() first, and then when there is error, use shutil.copy.

From: http://docs.python.org/library/shutil.html#shutil.copytree

If exception(s) occur, an Error is raised with a list of reasons.

So then you can decide what to do with it and implement your code to handle it.

import shutil, errno

def copyFile(src, dst):
    try:
        shutil.copytree(src, dst)
    # Depend what you need here to catch the problem
    except OSError as exc: 
        # File already exist
        if exc.errno == errno.EEXIST:
            shutil.copy(src, dst)
        # The dirtory does not exist
        if exc.errno == errno.ENOENT:
            shutil.copy(src, dst)
        else:
            raise

About .copy(): http://docs.python.org/library/shutil.html#shutil.copy

Copy the file src to the file or directory dst. If dst is a directory, a file with the same basename as src is created (or overwritten) in the directory specified. Permission bits are copied. src and dst are path names given as strings.

Edit: Maybe also look into distutils.dir_util.copy_tree
