Does this help?

<code>
#!python3
import csv

def unfussy_reader(csv_reader):
    while True:
        try:
            yield next(csv_reader)
        except csv.Error:
            # log the problem or whatever
            print("Problem with some row")
            continue

if __name__ == '__main__':
    #
    # Generate malformed csv file for
    # demonstration purposes
    #
    with open("temp.csv", "w") as fout:
        fout.write("abc,def\nghi\x00,klm\n123,456")

    #
    # Open the malformed file for reading, fire up a
    # conventional CSV reader over it, wrap that reader
    # in our "unfussy" generator and enumerate over that
    # generator.
    #
    with open("temp.csv") as fin:
        reader = unfussy_reader(csv.reader(fin))
        for n, row in enumerate(reader):
            print(n, "=>", row)
