Question

Write a program in Python that defines and calls the following use of defined functions:

1. COURIER_ADD(): It takes the values from the user and adds the details to a CSV file 'courier.csv’. Each record consists of a list with field elements as cid, s_name, Source, destination to store Courier ID, Sender name, Source, and destination address, respectively.
2. COURIER SEARCH(): Takes the destination as the input and displays all the courier records going to that destination. 

Answer 1

import csv
def COURIER_ADD():
cid=""
sname=""
src=""
dest=""
f= o p e n ( “ c o u r i e r .csv”,"w”,newline=")
courierwriter=csv.writer(f)
ans='y'
courierrec=[]
while ans=='y':
       cid=input(“Enter courier id :")
       sname=input(“Enter sender name:")
       src= input(“Enter source :")
       dest= input(“Enter destination :")
        rec=( cid,sname, src,dest)
        courierrec.append(rec)
         ans=input(“Continue(y/n)")
         courierwriter.writerows(courierrec)
         f.close()
def COURIER_SEARCH():
d=""
ds=""
ds=input(“Enter destination to search :")
with open(“courier.csv”, "r", newline=")
as fh:
      creader=csv.reader(fh)
      for rec in creader:
     d=str(rec[3])
if d==ds:
          print(rec)
fh.close()
COURIER_ADD()
COURIER_SEARCH()
