Copy is not happening

Guyz - I am having this problem where shutil.copy tree thinks a directory exists even though it doesnt..both the source and directory are local...first time i ran it ran without errors but the content is actually not copied,second time it ran it thinks the directory already exists,details below..please provide your inputs,if there are any other ways to copy other than shutil..please suggest

Firs time ran,without any errors but it was not actually copied

  <username:/local/mnt/workspace/username/Scripts>python test.py
    //local/mnt/workspace/loc/04.01.01.00.303_HY11/out
    //local/mnt/workspace/test/out
    copying

Rerun second time,it thinks it thinks directory exists

    <username:/local/mnt/workspace/username/Scripts>python test.py
    //local/mnt/workspace/loc/04.01.01.00.303_HY11/out
    //local/mnt/workspace/test/out
    copying
    Traceback (most recent call last):
      File "test.py", line 21, in <module>
        main()
      File "test.py", line 18, in main
        copytree(src,dst)
      File "test.py", line 11, in copytree
        shutil.copytree(s, d)
      File "/pkg/qct/software/python/2.5.2/.amd64_linux26/lib/python2.5/shutil.py", line 110, in copytree
        os.makedirs(dst)
      File "/pkg/qct/software/python/2.5.2/.amd64_linux26/lib/python2.5/os.py", line 171, in makedirs
        mkdir(name, mode)
    OSError: [Errno 17] File exists: '//local/mnt/workspace/test/out'
    <username:/local/mnt/workspace/username/Scripts>

Python code

import os,shutil

def copytree(src, dst, symlinks=False, ignore=None):
    for item in os.listdir(src):
        s = os.path.join(src, item)
        print s
        d = os.path.join(dst, item)
        print d
        if os.path.isdir(s):
            print "copying"
            shutil.copytree(s, d, symlinks, ignore)
        else:
            shutil.copy2(s, d)
def main ():
    src="//local/mnt/workspace/loc/04.01.01.00.303_HY11"
    dst="//local/mnt/workspace/test"
    copytree(src,dst)

if __name__ == '__main__':
    main()

Try this version, the destination directory will be automatically cleared...

import os,shutil,errno

def copytree(src, dst, symlinks=False, ignore=None):
    if os.path.exists(dst):
        shutil.rmtree(dst)

    os.mkdir(dst)

    for item in os.listdir(src):
        s = os.path.join(src, item)
        d = os.path.join(dst, item)
        print s + " >> " + d

        if ".git" in s:
            return

        if os.path.isdir(s):
            print "Copying directory..."

            try:
                copytree(s, d, symlinks, ignore)

            except OSError as e: 
                # File already exist
                if e.errno == errno.EEXIST:
                    print "Path exists : " + d
        else:
            shutil.copy2(s, d)

def main ():
    src="//local/mnt/workspace/loc/04.01.01.00.303_HY11"
    dst="//local/mnt/workspace/test"
    copytree(src,dst)

if __name__ == '__main__':
    main()

May I ask why don't you use shutil.copytree() instead? If you do want to have a wrapper around shutil.copytree() (for considering existing directory, for example) name your function different such as copytree_wrapper() (Because you are mixing your copytree with shutil.copytree, and recursion is not involving your copytree) The following works for me:

import os,shutil

def copytree_wrapper(src, dst, symlinks=False, ignore=None): ### Name it different, no confusion!
    for item in os.listdir(src):
        s = os.path.join(src, item)
        print (s)
        d = os.path.join(dst, item)
        print (d)
        if os.path.isdir(s):
            print ("copying")
            if not os.path.exists(d): ### Create directory if does not already exist 
                print ("directory '%s' created" % d)
                os.makedirs(d)
            copytree_wrapper(s, d, symlinks, ignore) ### shutil.copytree(s, d, symlinks, ignore)
        else:
            shutil.copy2(s, d)
def main ():
    src="/tmp/a"
    dst="/tmp/b"
    copytree_wrapper(src,dst)

if __name__ == '__main__':
    main()
