Question

What command would you use to change the turtle's pencolor to blue?

1) turtle.pencolor(blue)
2) turtle.pencolor('blue')
3) turtle.pencolor(0, 0, 255)
4) turtle.pencolor(0, 0, 1)

Answer 1

To change the turtle's pencolor to blue, you can use 'turtle.pencolor('blue')', 'turtle.pencolor(0, 0, 255)', or 'turtle.pencolor(0, 0, 1)'. Options 2 and 3 represent the RGB color model, but option 1 is the most straightforward method.

Step-by-step explanation:

To change the turtle's pencolor to blue in Python's turtle graphics module, you can use several commands. The correct commands are:

• turtle.pencolor('blue')
• turtle.pencolor(0, 0, 255)
• turtle.pencolor(0, 0, 1)

The second and the third options are using the RGB color model. In the second option, the maximum value (255) for blue is used, which represents the blue color. The third option is using RGB values between 0 and 1, where the value 1 stands for the blue color at its full intensity. Therefore, options 2) and 3) are also acceptable ways to set the color to blue besides option 1). However, option 1), which uses the color name as a string, is the most straightforward and commonly used method.
