IRA Python - Credit Card Rewards

Reward points are considered to be one of the most attractive benefits offered by credit cards. Whenever, one uses a credit card, a few reward points are credited in his/her account.

Write a program to define classes to create  a credit card object and a Customer object as per the following requirement.

A Credit Card has following attributes:

• card number (an alpha numeric value)

• name of the card holder (a string of characters)

• name of the Bank (a string of characters)

• date of expiry (a string in the format dd-mm-yyyy)

• card balance (a number value representing the existing credit amount on the card)

• a credit limit (a number value)

• reward benefit schemes - defines the applicable reward points earned per Rs 100 spent against a list of  items/services. Maintained in the form of key value pairs as "tuple of items: points earned".

For example:

If for a card, 3 Reward Points are added for every Rs.100 spent on

groceries and supermarkets along with 2 Reward Points for every

Rs. 100 spent on dining and telecom, it should be stored as follows:

{{ "groceries", "supermarkets"):3,

"dining", "telecom"):2}

Define a method in the class to initialize the attributes with given set of values when an object of the type is created . A Customer has a list of Credit Cards as attribute Define a method in the class to initialize the attributes with given set of values when an object of the type is created.

A Customer can use his/her credit cards to make payment for purchases (online/offline). Based on the amount to be paid on, customer chooses the card from

his/her credit card list, which has:

• Not expired yet

• has the maximum remaining credit balance.

• Payment amount is not beyond the remaining credit limit.

For example if a customer has following 4 credit cards:

1.card number : AX12345

name of the card holder : Ranjan Gogoi

name of the Bank :HDFC

date of expiry :01-05-2021

card balance : 200

credit limit:5000

Reward benefit Scheme: {(

“groceries", "supermarkets"):3, fodining"

,"telecom"):2)

2.card number : AB22345

name of the card holder : Ranjan Gogoi

name of the Bank :ICICI

date of expiry :01-05-2022

card balance: 8000

credit limit:10000

Reward benefit Scheme: {(

"groceries", "supermarkets"):3,( "dining

"telecom"):2)

3.card number: CBX3323490

name of the card holder: Ranjan Gogoi

name of the Bank SBI

date of expiry :01-05-2022

card balance : 20000

credit limit:50000

Reward benefit Scheme: (

"groceries", "supermarkets"):3,( "dining"

"telecom"):2)

4.card number : AXX22345

name of the card holder : Ranjan Gogoi

name of the Bank :AXIS

date of expiry :01-05-2022

card balance : 10000

credit limit:50000

Reward benefit Scheme: {(

":6-

"groceries", "supermarkets"): 3, (dining"

,"telecom"):2)

and the amount to be paid on 15-09-2021 is 3000, Customer will select the 4th card.

If customer is able to make the payment using a card, the card balance(Existing credit amount) is increased by the amount

spent. Also the reward points are credited to the cardholder's account based on the available reward benefit schemes of the card for the Item/Service for which the payment is made. If the item/services for which the card is to be used for payment is not in any of the reward benefit scheme's of the card, the default reward point will be considered as 1 per 100 Rupees spent.

Note:• To earn a credit point, a minimum of Rs 100 needs to be spent.

• All the string comparisons should be case insensitive.

Define a method in the class to calculate the reward points to be credited to the Customer's account for buying an item or making a payment using a credit card.

Method should fulfill the requirements defined above.

In case Customer does not have a valid Credit Card to make the payment, the reward points to be credited to the Customer's account will be considered as 0.

After defining the classes as described above, write the main section completely, in line to the "Sample input description section" mentioned below and to read the data in the same sequence

Sample input description:

Write code to read attribute values to create a list of objects of type Credit Card. 

a. Read a number for the count of Credit Card objects to be created and added to the list. 

b. Create a Credit Card object after reading the data related to it and add the object to the list of objects. For each Credit Card object read the values for:

• card number

• name of the card holder

• name of the Bank

• date of expiry

• card balance

• a credit limit

• reward benefit schemes - for this,

1. read a number (x) representing count of reward benefit schemes applicable

2. read a number (n) to be considered as count of items/services for which the reward point (n) earned is same per Rs 100 spent.

 3. read n number of strings (items /services) and create the tuple.

e. Using the Customer object created, calculate the reward points to be credited to the Customer's account for the payment details taken as input in point #c above.

f. Display a message "Reward points to be credited to the Customer's account =" (excluding the quotes). Print the reward point value calculated in the same line. 

For example:

Reward points to be credited to the Customer's account =200

In the next line, display a message "Card details after payment:" (excluding the quotes) 

g. Display the card number the remaining credit balance of the card and the card balance for all the Credit Cards created above one by one in separate

Values for the card number, the remaining credit balance and card balance should be separated by

For example:

Card details after payment:

Ax12345, 9000, 5000 

BCX223345, 1200D, 5000

Note: In the output the card details should appear in the same sequence as per input. You can use for the below given sample input and output to verify your solution using Test against Custom Input option in Hackarrank
