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.

The csv module does its own handling of newlines within Reader objects, so it wants the file object to pass along the newline characters unmodified. That's what newline='' tells the open function you want. Follow this answer to receive notifications. answered Dec 20, 2021 at 22:42.
In Python, while reading a CSV using the CSV module you can skip the first line using next() method.
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).
