    <p>I'm a beginning programmer who is building a program that simulates a bank with multiple bank accounts that a user can withdraw/deposit cash, create accounts, get exchange rates, etc. Currently, I'm trying to access a group of instances in my class that are all objects of my account class. The Account Manager class is responsible for managing these account objects and helping to organize them when user input is required. Right now, I'm trying to simulate my 3rd option on my menu which gets info on the account of a user's choice(they must manually put the ID of their account in in order to retrieve information on it, withdraw/deposit cash, etc.). Although I've managed to store all of these class instances in a list, I can't seem to use my get_account method to retrieve these for use. I'll post all of my code below. If you see anything else that is out of place, feel free to let me know. Code:</p> <pre><code># Virtual Bank # 3/21/13 # Account Manager Class class AccountManager(object): """Manages and handles accounts for user access""" # Initial def __init__(self): self.accounts = [] # create account def create_account(self, ID, bal = 0): # Check for uniqueness? Possible method/exception??? &lt;- Fix this account = Account(ID, bal) self.accounts.append(account) def get_account(self, ID): for account in self.accounts: if account.ID == ID: return account else: return "That is not a valid account. Sending you back to Menu()" Menu() class Account(object): """An interactive bank account.""" wallet = 0 # Initial def __init__(self, ID, bal): print("A new account has been created!") self.id = ID self.bal = bal def __str__(self): return "|Account Info| \nAccount ID: " + self.id + "\nAccount balance: $" + self.bal # Main AccManager = AccountManager() def Menu(): print( """ 0 - Leave the Virtual Bank 1 - Open a new account 2 - Get info on an account 3 - Withdraw money 4 - Deposit money 5 - Transfer money from one account to another 6 - Get exchange rates(Euro, Franc, Pounds, Yuan, Yen) """ ) # Add more if necessary choice = input("What would you like to do?: ") while choice != "0": if choice == "1": id_choice = input("What would you like your account to be named?: ") bal_choice = float(input("How much money would you like to deposit?(USD): ")) AccManager.create_account(ID = id_choice,bal = bal_choice) Menu() elif choice == "2": acc_choice = input("What account would you like to access?(ID only, please): ") AccManager.get_account(acc_choice) print(acc_choice) Menu() </code></pre>

    1. COI think KyleStrand tries to tell you that you should change `AccManager.get_account(acc_choice)` to `x = AccManager.get_account(acc_choice)` and then do `print(x)`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
