QUESTION

Using the below code as a template (bottom of the page) develop a Python 3 program which processes data stored in a list to display a specific arrangement of sheets on a billboard. You must develop the code to draw this logo across four billboard sheets.

THE PEPSI LOGO MUST BE DRAWN ACROSS FOUR SHEETS LIKE THIS:

Each sheet must be a rectangle measuring 200 x 500 pixels. The centerpoint of each location has been marked to help you position your images as you develop your program. Your sheets must fit precisely into the four locations indicated.

OTHER INFORMATION:

1. The provided template file also contains several data sets, in the form of lists, which specify how you must arrange the sheets when drawing them. These instruction lists each contain two types of data:

2. The template file also contains a dummy function definition, paste_up. Your task is to complete this function definition so that when called with a data set as its argument it draws the sheets at the locations and in the orientations specified. The function must work for any of the given data sets or any other similar data sets in the same format.

3. Your program must be able to draw four distinct sheets, each containing part of a single overall picture. Each sheet must be a 200 500 pixel rectangle and must be of a reasonable degree of complexity, involving multiple shapes and colours. The entire rectangle must be filled in with colour. Each sheet must be clearly distinct so that the viewer can tell which one has been drawn. It must be easy for the viewer to distinguish each sheet from its neighbours when they are side-by-side, either through the use of a visible margin or by contrasting background colours. Each sheet must be clearly different from all the others, regardless of their orientation, and the image on each sheet must be asymmetric so that it is easy to tell whether it is being displayed upright or upside down.

4. When pasted up correctly, as per the final two data sets provided, the separate parts of the image must align perfectly to produce a single, clearly recognisable, non-trivial picture. The title of the drawing canvas must describe the picture drawn.

5. Your code must be capable of drawing each of the four sheets at any of the four marked locations. The sheets must fit precisely into each of the locations marked on the billboards backing, with the entire area being filled and no parts of the drawing protruding. The sheets must be sufficiently different that it is easy to distinguish which one is being drawn in each location. The images on the sheets must preserve their integrity no matter where they are drawn. Your solution for relocating the sheets must work for all of the provided data sets and any other data sets in the same format. You cannot hardwire your code for specific data sets and you may not change the data sets provided.

6. Your code must be capable of drawing each of the four sheets in either of the two possible orientations, upright or upside down. The images on each sheet must be suffiently asymmetric that it is easy to tell one orientation from the other. The images on the sheets must preserve their integrity no matter how they are oriented. Your solution for reorienting the sheets must work for all of the provided data sets and any other data sets in the same format. You cannot hardwire your code for specific data sets and you may not change the data sets provided.

7. Code must be presented professionally. In particular, given the obscure and repetitive nature of IFB104 Building IT Systems Semester 2, 2017 the code needed to draw complex images using Turtle graphics, each significant code segment must be clearly commented to say what it does, e.g., Draw letter M, Draw red oval, etc.

8. You must complete the billboard logo using basic Turtle graphics and maths functions only. You may not import any additional modules or files into your program other than those already included in the given billboard.py template. In particular, you may not import any image files for use in creating your picture.

#-----Test Data------------------------------------------------------# # # The list in this section contains the data sets you will use to # test your code.

The location to paste the sheet, from 'Location 1' to # 'Location 4' # 3. The sheet's orientation, either 'Upright' or 'Upside down' # # Each data set does not necessarily mention all four sheets. # # In addition there is an extra value, either 'X' or 'O' at the # start of each data set. The purpose of this value will be # revealed only in Part B of the assignment. You should ignore it # while completing Part A. # # You can create further data sets, but do not change any of the # given ones below because they will be used to test your submission. # # Note that your solution must work for all the data sets below # AND ANY OTHER DATA SETS IN THE SAME FORMAT! #

# Paste the sheets onto the billboard as per the provided data set def paste_up(dummy_parameter): pass

#-----Main Program---------------------------------------------------# # # This main program sets up the background, ready for you to start # drawing your billboard. Do not change any of this code except # where indicated by comments marked '*****'. #

# Set up the drawing canvas # ***** Change the default argument to False if you don't want to # ***** display the center points of each sheet on the backing create_drawing_canvas()

# Control the drawing speed # ***** Modify the following argument if you want to adjust # ***** the drawing speed speed('fastest')

# Decide whether or not to show the drawing being done step-by-step # ***** Set the following argument to False if you don't want to wait # ***** while the cursor moves around the screen tracer(True)

# Give the drawing canvas a title # ***** Replace this title with one that describes the image # ***** displayed on your billboard when the sheets are pasted # ***** correctly title("Describe your billboard's image here")

### Call the student's function to display the billboard ### ***** Change the number in the argument to this function ### ***** to test your code with a different data set paste_up(data_sets[0])

# Exit gracefully release_drawing_canvas()

I HAD TO CHANGE 9 'CENTRE' WORDS TO 'CENTER' WITHIN THE CODE AS IT WOULD NOT LET ME POST THE QUESTION WITH 'CENTRE' IN THE CODE
