Answer 1

The right solution is to use csv parser(i didn’t test this code):

writer = csv.writer(open('corrected.csv'))
for row in csv.reader('myfile.csv'):
    if not row[0].startswith('1VDV-constatomGlu-final-NoGluWat.'):
        writer.writerow(row)
writer.close()

You can use also regular expression or some string manipulations but there is the risk that after your transformations the file will be no longer in csv format
