Write a class C2 that inherits all the functionality of A2 and B2,

// with the same stipulation that it should take f() from A2 and g() from B2.

Write a class named "BankAccount" with the following attributes: id, currency and balance. The class has a constructor with only two of the attributes: id and currency. The value of the currency, if omitted, has a default value "EUR0". The third attribute by default is zero. We suppose that when we activate a bank account its balance is initially empty.

Task 2:

Write a Python class named "Calculator" that has no attributes.The class has only one method named "performOperation()" that takes in input three parameters, two numeric values (A and B) and one string value representing one of the four basic mathematical operations (+","", "*" or "/"). For each operation, it returns the result of the respective operation for the two numbers. In case the second value is zero and the operation is "/", the method returns a string message "Error: Can not divide by zero". If the operation is not as expected, the method returns a string message "Error: Operation not supported".

Write a Python class named "Pencil" that has three attributes: brand (string), color (string), thickness (int).

The class must include a constructor method that initializes each variable to an appropriate value, and the class should include methods for setting the value of each type and retrieving the value of each type.

Apply discounts on the following basis,

• 5%, if the customer stays more than 2 days
• 15%, if the customer stays more than 5 days

Input

• The first line of input contains a number dayCharge
• The second line of input contains a number days
