Question

QUESTION 1 To mimic a real-world programming situation, you are given partially-completed code, written by a former employee you have just replaced. Your task is to complete the program he was developing. Fortunately, the former employee's documentation is up-to-date and quite useful. (He must have been a QUT student!) Below is the incomplete section of the code, taken from the Python program which is to use Turtle to draw a grid. (In this exercise, a grid is a series of rows, and a row is a series of boxes or squares.) To draw a grid, each box (square) is drawn starting and finishing at the top left hand corner of the box, heading east (right). A series of boxes drawn ina line from left to right form a row. Each subsequent row is drawn underneath the previous row The number of rows to be drawn is stored in the variable: number of rows. The number of boxes to be drawn in each row is stored in the variable: number of columns. The existing function goto_next_box_pos () takes care of repositioning the turtle to where the next box in the row is to be drawn. The existing function goto next row pos () takes care of repositioning the turtle to where the next row is to be drawn. Here's the incomplete code. The only missing part is a condition. You can safely assume that all of the other code your predecessor wrote is complete and correct. # draw a series f rows of boxes for each row in range (number of_rows): # draw a serie3 of boxe 3 in a horizontal line for each column in range (number of columns): draw grey box () else: draw white box) goto next box pos () goto next row pos () Complete the code so that the first column is shaded, then every second column is shaded. The image below gives an example of the shading pattern required NB: The % operator returns the remainder after integer division.

The question blank can be filled in with any of these

Thanks for your assistance!

Answer 1

Answer

if ((each_row + each_column) % 2) == 0
