Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
Started with C:/Steve/.pythonrc
  >>> import os
  >>> dirfrom = 'C:\\Steve\\t1'
  >>> dirto = 'C:\\Steve\\t2\\'
  >>> copy_command = 'copy "%s" "%s"' % (dirfrom, dirto)
  >>> if os.system(copy_command) == 0:
  ...   print 'yay!'
  ... else:
  ...   print 'boo!'
  ...
C:\Steve\t1\hello.txt
         1 file(s) copied.
yay!
  >>>
