Copy files to folder up one directory in python

Question

I have a folder with several files that I would like to copy to a single directory (there are also some files in this folder that I do not want to copy). I know that there is a os.chdir ("..") command to move me to a directory. However, I am not sure how to copy the files that I need into this directory. Any help would be greatly appreciated.

UPDATE:

This is what I have now:

from shutil import copytree, ignore_patterns

copytree("/Users/aaron/Desktop/test/", "/Users/aaron/Desktop/", ignore=ignore_patterns('*.py', '*.txt'))

I get the following error:

Traceback (most recent call last):
  File "update.py", line 61, in <module>
    copytree("/Users/aaron/Desktop/test/", "/Users/aaron/Desktop/", ignore=ignore_patterns('*.py', '*.txt'))
  File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/shutil.py", line 146, in copytree
    os.makedirs(dst)

    mkdir(name, mode)

shutil , copyfile, copy, copy2 copytree. http://docs.python.org/library/shutil.html

, - :

import os
import shutil

fileList = os.listdir('path/to/source_dir')
fileList = ['path/to/source_dir/'+filename for filename in fileList]

for f in fileList:
    shutil.copy2(f, 'path/to/dest_dir/')

, , os.listdir(). ,

fileList = [filename for filename in os.listdir('path/to/source_dir') if filename[-3] is '.txt']

fileList = os.listdir('path/to/source_dir'), .txt
