import csv
import sys

maxInt = sys.maxsize
decrement = True

while decrement:
    # decrease the maxInt value by factor 10
    # as long as the OverflowError occurs.

    decrement = False
    try:
        csv.field_size_limit(maxInt)
    except OverflowError:
        maxInt = int(maxInt / 10)
        decrement = True
