For this python program we are going to use the sample csv file from . You can download the file from here -- Sample CSV File.

There are 6 records in this sample csv. Each record has 5 data fields, First Name, Last name, address, 4th attribute is I think its landmark (but doesn't matter), 5th data attribute is zipcode.

import csv
def read_csv(filename):
        f = open(filename, "r")
        records = list(csv.reader(f))
        return records
    except Exception as e:
        return False

filename = "sample csv file.csv" records = read_csv(filename) for record in records: print(record) print(f"{len(records)} records read from csv file : {filename}")


['John', 'Doe', '120 jefferson st.', 'Riverside', ' NJ', ' 08075']
['Jack', 'McGinnis', '220 hobo Av.', 'Phila', ' PA', '09119']
['John "Da Man"', 'Repici', '120 Jefferson St.', 'Riverside', ' NJ', '08075']
['Stephen', 'Tyler', '7452 Terrace "At the Plaza" road', 'SomeTown', 'SD', ' 91234']
['', 'Blankman', '', 'SomeTown', ' SD', ' 00298']
