Use file.readline() or .readlines() and then process one line at a
time.

I assume that the drive letters will be directly after a single quote.
You need this re:

reDriveLetter = re.compile(r"(? <=')[A-Z](?=:\\)").

You can try reDriveLetter.f indall() or the reDriveLetter.f inditer()
functions then, each match object will match a single capital letter.

Very important to everyone working with regular expressions: the
redemo.py script. Search for a Scripts directory in your python
directories (it's under Tools on Windows, otherwise get it from the
source distribution), redemo.py is in there along with other useful
scripts.
