Question
Create a class called `Bank` and pass `ABC` to it. 2. Inside the class you have to define two methods: - 2.1: Define a function
Create a class called `Bank` and pass `ABC` to it.
2. Inside the class you have to define two methods:
- 2.1: Define a function called `basicinfo()` and add a print statement inside it saying
`"This is a generic bank"` and returning the string `"Generic bank: 0"`.
- 2.2: Define a second function called `withdraw` and keep it empty by adding a pass keyword under it.
Make this function abstract by adding `'@abstractmethod'` right above it.
3. Create another class called `Swiss` and pass the class `Bank` inside it.
This means you are inheriting from `class Bank`.
- 3.1: Create a constructor for this class that initializes a class variable `bal` to `1000`
4. Override both functions from the Bank class: `basicinfo()` and `withdraw()`.
- 4.1: Define a function called `basicinfo()` and add a print statement inside it stating `This is the Swiss Bank`
and returning a string with `"Swiss Bank: "` followed by the current bank balance.
For example, if `self.bal = 80`, then it would return `"Swiss Bank: 80"`
- 4.2 Define a second function, called `withdraw` and pass one parameter to it (other than `self):` amount.
Amount represents the amount that will be withdrawn.
- 4.2.1: Update the class variable bal by deducting the value of amount from it.
- 4.2.2: Print the value of amount giving output such as: Withdrawn amount: 30"
- 4.2.3: Print the new balance giving an output such as: New balance: 970
- 4.2.4: Return the new balance
- Note: Make sure to verify that there is enough money to withdraw!
If amount is greater than balance, then do not deduct any money from the
class variable `bal`. Instead, print a statement saying `"Insufficient funds"`, and return the original account balance instead.
# Import ABC and abstractmethod from the module abc (which stands for abstract base classes)
from abc import ABC, abstractmethod
# Class Bank
class Bank(''' YOUR CODE HERE '''):
""" An abstract bank class
[IMPLEMENT ME]
1. This class must derive from class ABC
2. Write a basicinfo() function that prints out "This is a generic bank" and
returns the string "Generic bank: 0"
3. Define a second function called withdraw and keep it empty by
adding the `pass` keyword under it. Make this function abstract by
adding an '@abstractmethod' tag right above the function declaration.

# Class Swiss
class Swiss('''YOUR CODE HERE'''):
""" A specific type of bank than derives from class Bank
[IMPLEMENT ME]
1. This class must derive from class Bank
2. Create a constructor for this class that initializes a class
variable `bal` to 1000
3. Implement the basicinfo() function so that it prints "This is the
Swiss Bank" and returns a string with "Swiss Bank: " (don't forget
the space after the colon) followed by the current bank balance.
For example, if self.bal = 80, then it would return "Swiss Bank: 80"
4. Implement withdraw so that it takes one argument (in addition to
self) that is an integer which represents the amount to be withdrawn
from the bank. Deduct the withdrawn amount from the bank bal, print
the withdrawn amount ("Withdrawn amount: {amount}"), print the new
balance ("New Balance: {self.bal}"), and return the new balance.
Note: Make sure to verify that there is enough money to withdraw!
If amount is greater than balance, then do not deduct any
money from the class variable `bal`. Instead, print a
statement saying `"Insufficient funds"`, and return the
original account balance instead.
