Saving class instances to a file and reading from it (OOP) [duplicate]

So i am fairly new to OOP in Python, and as an excercise, I wrote a simple "Bank" program, and it works. The obstacle is when I create an instance to the Account class, i want to save it in some text file, and be able to read existing instances from it. For example: *I create 10 accounts, and when I kill the program, I want for them to save the instance data to a file, and when I open it again, I want to be able to import it and use it as previously * Here is the code I wrote:

class Account:
    def __init__(self,name,password,amount):
        self.name = name
        self.password = password
        self.amount = amount
    def display(self):
        print(self.name, self.amount)
    def withdraw(self, new_amount):
        if new_amount < self.amount and new_amount > 0:
            self.amount -=new_amount
        else:
            raise ValueError('Amount must be greater than 0 and less than current amount')
    def deposit(self,new_amount):
        if new_amount>0:
            self.amount += new_amount
        else:
            raise ValueError('Amount must be greater than 0')

Hope you all can help me!
