Question

Write a python program that has:

1. function createCustomerRecord that has 1 parameter, the filename to read from, the method then reads all the records from the file and returns a dictionary. Each record in the file has the following format

CivilIdNumber

Name

Telephone#    

Address

CivilIdNumber

Name

Telephone#    

Address

CivilIdNumber

Name

Telephone#    

Address

Etc

A record always consists of 4 lines (civilid, name, telephone and address). You can find a sample input file on last page of this assignment, copy it and past it into a .txt file and save it to the same directory that your python program resides on.

The function then creates a dictionary with the civilIdNuber as the key and the rest of the record as a list with index 0 being the name, index 1 being the telephone# and index 2 being Address.

When finishing reading all records the function then returns the dictionary

2. Write a function printCustomerRecord that has 2 parameters, a dictionary of the customer record and the output filename, the function will then print to the output file, the dictionary in the following format

CivilId: civilidnumber

Name: name

Address: address

Telephone Number: telephone

CivilId: civilidnumber

Name: name

Address: address

Telephone Number: telephone

Etc…

3. Write a main function that will print to the screen ‘Hello’, then call function createCistomerRecord and pass it the input file name then call function printCustomerRecord and pass it the dictionary and the output file name. Then finally print to the screen ‘goodbye’

4. Call the main function.

I have satisfied all the requirements of the question and I'm providing the screenshots of code and output for your reference...

Code:

import re

def createCustomerRecord(filename):
    f = open(filename)
    content = f.read()
    content = re.split("\\n", content)
    content.pop()
    customerRecords = {}
    record = []
    for i in range(len(content)):
        if i % 4 == 0:
            key = content[i]
            record = []
        else:
            record.append(content[i])
            customerRecords[key] = record
    return customerRecords


def printCustomerRecord(dict, filename):
    f = open(filename, "w+")
    for key in dict.keys():
        f.write("CivilId: " + key + "\n")
        f.write("Name: " + dict[key][0] + "\n")
        f.write("Address: " + dict[key][2] + "\n")
        f.write("Telephone Number:" + dict[key][1] + "\n")


def main():
    print("Hello")
    printCustomerRecord(createCustomerRecord("input.txt"), "Output.txt")
    print("goodbye")


if __name__ == "__main__":
    main()
