5. draw_pattern_version1(a_canvas, pattern_list, size, left, top) This function is passed five parameters: the Canvas object, a list of string elements, followed by three integer parameters. The function draws a grid of coloured rectangles inside the canvas area. The left-top position of the grid of coloured rectangles is given by the last two parameter values and the size of each rectangle is given by the size parameter. Each element of the pattern_list parameter is a string of digits and each element corresponds to one row of coloured rectangles. Each digit of the string element dictates the colour of the rectangle, e.g., the digit 1 means that the rectangle is filled with red, the digit 2 means that the rectangle is filled with blue, the digit 3 means that the rectangle is filled with green, etc. Note that the first two lines of this function are (you may use any colours of your choice): possible digits "12345" colours["red", "blue", "green", "yellow", "black" Once you have completed this function you should see rows of coloured rectangles (of varying lengths) on the left hand side of the canvas area. . 6. draw_pattern_version2(a_canvas, pattern_list, size, left, top, longest_width) This function is passed six parameters: the Canvas object, a list of string elements, followed by four integer parameters. Inside the canvas area the function draws a mirror image of the grid of coloured rectangles drawn in Part 5. above, i.e., if you were to fold the canvas down the middle line each coloured square lies exactly over a square of the same colour. Note that the first two lines of this function are (use the same colours as you used in Part 6. above): possible digits - "12345 colours- ["red", "blue", "green", "yellow", "black"] Once you have completed this function and you test your program, you should see a mirror image of the Part 5. grid of coloured squares on the right hand side of the Canvas area. The program skeleton: The skeleton of this assignment program is shown below. You need to define five of the function:s and make one small change to the main() function.
