What is a CSV?
Comma Separated Values- (CSV) is a simple file format used to store tabular data, such as a spreadsheet or database. A Comma Separated Values- (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas.
csv.reader()
csvreader is an iterable object. Hence, .next() method returns the current row and advances the iterator to the next row.
csv.writer()
The file object is named as csvfile. The file object is converted to csv.writer object. We save the csv.writer object as csvwriter.
Program
import csv
with open("user_info.csv", "w") as obj:
fileobj = csv.writer(obj)
fileobj.writerow(["User Id", "password"])
while(True):
user_id = input("enter id: ")
password = input("enter password: ")
record = [user_id, password]
fileobj.writerow(record)
x = input("press Y/y to continue and N/n to terminate the program\n")
if x in "Nn":
break
elif x in "Yy":
continue
with open("user_info.csv", "r") as obj2:
fileobj2 = csv.reader(obj2)
given = input("enter the user id to be searched\n")
for i in fileobj2:
next(fileobj2)
# print(i,given)
if i[0] == given:
print(i[1])
break
