In this final, most complicated challenge the reader needs to create a complete program that could be used by an art gallery to store a list of the art and artists in their collection. This should be stored in a relational SQL database which can be accessed by a graphical user interface.

In this challenge the reader must create a graphical user interface, which will display the times tables and will need to use the following skills: loops (while and for), subprograms and the Tkinter library.

For this challenge, the reader needs to create a program that will store the user ID and passwords for the users of a system in a .csv file. The skills they need include: input and display data, lists, if statements, loops (while and for), subprograms and saving to and reading from a .csv file.

This is the first of the five chunky challenges that are created to allow the reader to practice all the skills they have learnt in a larger program that will take longer to complete. In this challenge the reader must create a program that will encode or decode a message using a shift code. The skills they will need include: input and display data, lists, splitting and joining strings, if statements, loops (while and for) and subprograms.

In this chunky challenge the reader makes an on-screen version of the board game “Mastermind”. The computer will automatically generate four colours from a list of possible colours, which the user must guess correctly to win the game. The skills they need include: input and display data, lists, random choice from a list, if statements, loops (while and for) and subprograms.
