LLOYDS BANK ACCOUNT SYSTEM
The development of the joint account opening system application for the Lloyds Bank
was indeed a matter of sheer challenge. The first and foremost query regarding this that was
needed to be resolved was that whether the application was going to have a graphical user
interface or should be provided with a text based interface.
The program for this application has been developed using the Python programming
language. The usability of python for one such program helped greatly in the process of
simplifying the matters. Python is a very simple language that can be easily learnt and used
by the beginners. The best thing about python is that the keywords used in it are fairly simple
and understandable. In this case the program was broken down into several stages or sections.
The main aim or the problem statement for this program comprised of building a system that
can allow two customers of the bank to open a joint account with the Lloyds. The system is
supposed to record all the data entered by the customers and then save them locally using a
file management system.
Conditional statements and iterative loop statements provided great assistance in the
process of developing the distinctive structure for the development of different cycles of
inputs over the same for both the customers who are in line for the joint venture. The program
displays clear messages to guide the user to enter valid data into the respective form input
elements. While loops with respective conditions have been used to resolve this problem
where the users either miss out on entering a value to an important field or where invalid
inputs are registered. The system checks for these invalid or null entries and asks the users to
re-input.
The use of file handling was a real challenge for this task. It was required to be
analysed of how many files are to be maintained for the storage of all necessary data in a
chronological or readable manner. Each file used for a particular section has been so

programmed to store the details of both the customers in a proper grouped fashion with clean
labels of the inputs. The files have been given clearly presented names.
Various array lists and different types of data have been used to build this program to
suffice the data needs of the form system. One crucial design consideration was to how the
checkbox inputs are supposed to be handled by the text-based program. It was finally decided
to use array stored elements and menu items to validate the inputs of the users against several
Ýes’/’No’ options or multiple choice answers.
