no, it isn't, it is far more insidious.

def CopyFiles(dirname,fnamelist):
    for name in fnamelist:
        destFile = open((dirname+"""\"""+name),'w')
        srcFile = open(name,"r")
        destFile.write(srcFile.read())
        srcFile.close()
        destFile.close()

note the backslash in the open() call.  This yields """, an escaped ", "" so 
python keeps looking for the end of the triple quoted string.

import os.path
os.path.join(dirname, name)

solves it.
