print "\n" print "TRANSACTION COMPLETED"

You need quotes around string literals, pieces of text that were never assigned a name.

She did have quotes. This is what you apparently saw:

This is what I saw (there are single quotes around each string literal):

              def MenuOption(self, option, Account):
                            if option == 1:
        print ‘\n’
        Account.deposit(input(“Deposit amount: $”))
        print ‘\n’
        print ‘TRANSACTION COMPLETED’
        print ‘\n’
    elif option == 2:
        print ‘\n’
        Account.withdraw(input(“Withdraw amount: $”))
        print ‘\n’
        print ‘TRANSACTION COMPLETED’
        print ‘\n’
    elif option == 3:
        print ‘\n’
        Account.trans()
        print ‘\n’
        print ‘QUERY COMPLETED’
        print ‘\n’

I suspect the elif problems come from using a mix of tabs and spaces in lining things up. Python uses 8 spaces per tab, but your editor could be different. If your editor was using tab stops of four spaces, you could mix tabs and spaces in a way that looked reasonable in your editor, but looks unreasonable to the Python compiler.

If indeed that is the problem, then this is also the problem with the print statement. I see no other error - could be missing something though.
