Need help with pseuo -bank account using OOP

[obieze998]

Again, this is bad format. You are checking each account's pin, requiring you to repeat code and requiring you to add code every time you add an account.

Your data global is backwards. The pins should be the keys, the accounts should be the values. Then you can see if the pin is in the data (pin in data not pin == data), and get the account out of the data with data[pin]. Then you take that account and run it through ONE set of code that checks for withdrawl or deposit.

d1 = 0
d2 = 0
d3 = 0
y1 = 0
w1 = 0
pin = 0
class Bank_Account: 
    def pincheck(self, pin):
       if pin in  data:
           data[pin]
           return True
       else:
          return False
     # constructor or initializer
    def __init__(self, name, money, pin1):
         self.__name = name
         self.__balance = money   # __balance is private now, so it is only accessible inside the class
         self.__pin = pin1
         

    def deposit(self, money):
         self.__balance += money
 
    def withdraw(self, money):
         if self.__balance > money :
             self.__balance -= money
             return money
         else:
             return "Insufficient funds"
 
    def checkbalance(self):
         return self.__balance
    def next_step():
        while True:
              y2 = int(input("Enter 1 if you want to make a withdrawal, enter 2 if you don't"))
        if y2 == 1:
           enter_pin()
        else:
            print("ERROR, TRY AGAIN")


Bone = Bank_Account('Obi Ezeakachi', 5000, 1111) 
Btwo = Bank_Account('Tasha St.Patrick', 80000 , 2222)
Bthree = Bank_Account('Tommy Egan', 7000, 3333)

data = {'1111':  Bone  , '2222' :  Btwo , '3333' :  Bthree }
data = {int(pin):value for key, value in data.items()}

def enter_pin():
     while True:
      pin = int( input("Enter pin "))
      if pin in data:
         data[pin]
         return True
      else:
       print("INCORRECT PIN TRY AGAIN")

enter_pin()

if Bone.pincheck(pin):
   
   print("Obi Ezeakachi: £",Bone.checkbalance())
   y1 = int(input("Enter 1 if you for a withdrawal, enter 2 if you don't"))
if y1 == 1:
   w1 = input("How much do you want withdraw")
   int(w1)
   print("Withdrawal: £",Bone.withdraw(w1))
   print("Current Balance:",Bone.checkbalance())
   next_step()
else:
   d1 = int(input("How much do you want to deposit"))   
   Bone.deposit(d1)   
   print("Current Balance:",Bone.checkbalance())
   next_step()
if Btwo.pincheck(pin):
   print("Tasha St.Patrick:",Btwo.checkbalance())
y1 = int(input("Enter 1 if you want to make a withdrawal, enter 2 if you don't"))
if y1 == 1:
   w2= int(input("How much do you want to withdraw"))
   print(Btwo.withdraw(w2))
else:
   d2= int(input("How much do you want to deposit"))
   Btwo.deposit(d2)
   print("Current Balance:",Btwo.checkbalance())
   next_step()
if Bthree.pincheck(pin):
    
   print("Tommy Egan:",Bthree.checkbalance())
y1 = int(input("Enter 1 if you want to make a withdrawal, enter 2 if you don't"))   
if y1 == 1:
   w3= int(input("How much do you want to withdraw"))
   print("Withdrawal:",Bthree.withdraw(w3))
   next_step()
else:
   d3= int(input("How much do you want to deposit"))
   Bthree.deposit(d3) 
   print("Current Balance:",Bthree.checkbalance())
   next_step()

This is what I've done so far. But i'm still a bit confused by what you mean by running it through a one set set of code, my own existing code that checks for deposits or withdrawals. Or make a new section of code that does this.
