Python - break a large mysql dump into small dumps

# created a dumpfile from my mysql db
# and found that it was too large to
# upload to my new db host.
 
# this python script breaks up the database
# into smaller pieces that you can more
# easily import through phpmyadmin
# (if I'd only had shell access I wouldn't
# have this problem at all!)
 
# indicates a new table is about to be
# created
dlmtr = "-- Table structure for table"

for line in wholeFile:
    if line.find(dlmtr) > -1:
        # this is the seam for the next file
        print "starting new file"
        oFile.close()
        fileN += 1
