Question

Please use python Programming Language:

Select one of the following topics:

• Band
• Character
• Account

Create a class based on your chosen topic. Make sure to include at least four attributes of varying types, a constructor, getters/setters for each attribute w/input validation, a toString, a static attribute, and a static method.

Then, create a function (outside of your class) that connects to a text file which should contain the attributes of several objects. Read the data from the file, use the data to instantiate your objects, then return them in a list.  

In main(), call your function and demonstrate some methods of object from the returned list.

Note: Please use python Programming Language.

Python Program:

class Account:
   """ Account class """
   # Static variable
   bank = 'ABC Corporation'
   def __init__(self, id=0, name="", bal=100, intRate=0):
       """ Default Constructor """
       self._id = id;
       self._name = name;
       self._bal = bal;
       self._intRate = intRate;
      
   def setId(self, id):
       """ Setter method for id """
       self._id = id;
  
   def getId(self):
       """ Getter method for id """
       return self._id;
  
   def setName(self, name):
       """ Setter method for name """
       self._name = name;
  
   def getName(self):
       """ Getter method for name """
       return self._name;
  
   def setBal(self, bal):
       """ Setter method for balance """
       self._bal = bal;
  
   def getBal(self):
       """ Getter method for balance """
       return self._bal;
      
   def setIntRate(self, intRate):
       """ Setter method for interest rate """
       self._intRate = intRate;
  
   def getIntRate(self):
       """ Getter method for interest rate """
       return self._intRate;
  
   def __str__(self):
       """ Overriding toString method """
       return ("ID: " + str(self._id) + "\nName: " + self._name + "\nBalance: " + str(self._bal) + "\nInterest Rate: " + str(self._intRate))
      
   @staticmethod
   def getBank():
       return Account.bank  
      
      
      
# Main function that creates objects from text file
def main():
   accObjs = []
   # Opening file for reading
   with open("d:\\Python\\acc.txt") as fp:
       # Iterating over line by line
       for line in fp:
           cols = line.strip().split()
           # Creating account object
           aObj = Account(int(cols[0]), cols[1], float(cols[2]), float(cols[3]))
           # Adding to list
           accObjs.append(aObj)
              
   print("\nBank Name: " + Account.getBank() + "\n\n")
   # Printing objects
   for aObj in accObjs:
       print(aObj)
       print("\n")

# Main function calling
main()
