Normally, you want to process the file line by line. Is this the case for you,
too? Then, you can use the following pattern:

f = open("foo")
for line in f.xreadlines():
    # Get rid of any trailing whitespace, including CR and LF characters
    line = line.rstrip()
    # do something with the line now
f.close()

There is no need to read the whole file and split it at line endings, the
readlines() and xreadlines() methods of file objects are invented just for
that.

Yes. I already recommended the MySQLdb module to you, which will work fine on
Windows and Unix. If you can spare a few euros, you can get a commercial
license for mxODBC. This is an ODBC solution that will also work on Unixen.  If
you target MySQL only, MySQLdb is the way to go. Everything else is
superfluous, and doesn't have any technical advantages.
