Getting "newline inside string" while reading the csv file in Python?

Question

I have this utils.py file in Django Architecture:

def range_data(ip):
    r = []
    f = open(os.path.join(settings.PROJECT_ROOT, 'static', 'csv ', 
                          'GeoIPCountryWhois.csv'))
    for num,row in enumerate(csv.reader(f)):
        if row[0] <= ip <= row[1]:
            r.append([r[4]])
            return r
        else:
            continue
    return r

Here the ip parameter is just the IPv4 Address, I am using open source MAXMIND GeoIPCountrywhois.csv file.

Some starting content of GeopIOCountrywhois.csv:

"1.0.0.0","1.0.0.255","16777216","16777471","AU","Australia"
"1.0.1.0","1.0.3.255","16777472","16778239","CN","China"
"1.0.4.0","1.0.7.255","16778240","16779263","AU","Australia"
"1.0.8.0","1.0.15.255","16779264","16781311","CN","China"
"1.0.16.0","1.0.31.255","16781312","16785407","JP","Japan"
"1.0.32.0","1.0.63.255","16785408","16793599","CN","China"
"1.0.64.0","1.0.127.255","16793600","16809983","JP","Japan"
"1.0.128.0","1.0.255.255","16809984","16842751","TH","Thailand"

I have also read about the issue, But didn't found so much understandable. Would you please help me to solve that error?

According to my method in utils, I am checking country name of paasing parameter IP address to the method.

Answer 1

had similar problem earlier today, there was an end quote missing from a line and the solution is by instructing reader to perform no special processing of quote characters (quoting=csv.QUOTE_NONE).
