homedir, file copy

[ecu_jon]

hello,
i am trying to work with windows homedirectory as a starting point for
some kind of file copy command. i'm testing this on a win7 box so my
home is c:\Users\jon\
here is the code snippet i am working on:

import os

homedir = os.path.expanduser('~')
try:
    from win32com.shell import shellcon, shell
    homedir = shell.SHGetFolderPath(0, shellcon.CSIDL_APPDATA, 0, 0)

except ImportError:
    homedir = os.path.expanduser("~")
print homedir
print os.listdir(homedir+"\\backup\\")
homedir.replace("\\\\" , "\\")
print homedir
shutil.copy (homedir+"\\backup\\", homedir+"\\backup2\\")


output looks like:
C:\Users\jon
['test1.txt', 'test2.txt']
C:\Users\jon

Traceback (most recent call last):
  File "D:\spring 11\capstone-project\date.py", line 43, in <module>
    shutil.copy (homedir+"\\backup\\", homedir+"\\backup2\\")
  File "C:\Python27\lib\shutil.py", line 116, in copy
    copyfile(src, dst)
  File "C:\Python27\lib\shutil.py", line 81, in copyfile
    with open(src, 'rb') as fsrc:
IOError: [Errno 2] No such file or directory: 'C:\\Users\\jon\\backup\
\'


why is there still two \\ in the pathfor the copy command?
