[Solved] XML Parsing Problem with Python

XML Parsing: Create class CreditCard with the following abstract method:

def credit_points(self)

The above abstract method derived in every child class, and print the respective credit points for a selected credit card.

Create four classes Visa, Master, Platinum, Titanium.
Override Abstract Method of the base class i.e CreditCard.

Create a program and write the main block to test the above class. 
Print the menu of the Credit Card list, assume that all the credit cards are for HDFC bank. Then select your choice from the defined menu, and print the credit points
for the selected credit cards, after reading the XML file (“creditCard.xml”).

Note:
1) Assume that all the credit points on spend of every 200 Rs.
2) XML file name= “creditCard.xml”.

Note:
The XML file format:
<CreditCard>
    <card>
        <name>creditCard1</name>    
        <creditPoints>2</creditPoints>
    </card>
    <card>
        <name>creditCard1</name>
            <creditPoints>7</creditPoints>
        </card>
<CreditCard>
