![]() The Random and String modules are predefined and the tkintermodule should already be available on your system as it is a built-in module deployed with the Python installation routine. This Python password generator requires no extra installation of modules. We are, however, introducing a couple of new concepts, but 90% of what we are looking at today is stuff we have already covered in our earlier articles. This is a very simple program, that is not to say that there are no significant complexities in it, in fact as computer programs go this is not that much higher up the evolutionary tree than the ubuquitious “hello world”. Why is this called a non-functional requirement? It is because the program will work perfectly well from the CLI, we will be able to enforce the combination of differing characters and minimum password length, but all the the graphical interface brings to the party is a simplicity of use. The program will be run with a graphical interface for ease of use.Therefore, we have the following non-functional requirement The password will be a minimum of 10 characters, unless a longer one is requested.Īs we have already shown we could just have this program work from the command line, but it is a fact of modern life, 99% of the world uses a graphical interface to interact with their devices, so this will require a graphical interface.The password will contain a mixture of all four.The password must contain a combination of lowercase, uppercase, symbols, and digits. ![]() We have the following functional requirements that must be included in the program. Therefore, your manager has tasked you with creating a Random Password Generator to be issued to staff to create complex passwords you have decided to use Python to carry out this task. It has become apparent that many personal in your company are using passwords that are too simple, we know that passwords are a critical part of a secure authentication process, they prevent unauthorised access to critical company information. What we are going to look at today is building an interactive password generator, this will be more complicated than the command line version we wrote in our last article. It is now time to start looking at doing something useful with the program. Our last article was the last to be focused on a single concept the Package, this means that we have effectively finished learning the basics.

Print("Password generated: ".format(password_index, randomize_password(password)))Īnd the output is… How many passwords do you want to generate? 3 Password = password + random.choice(characters)
