Exploring Turtle Graphics in Python

What is the primary purpose of the `penup()` function in Turtle graphics?

• To change the colour of the turtle's pen

• To lift the pen so it doesn't draw on the canvas

• To increase the speed of the turtle

• To reset the turtle's position

Which function is used to draw a circle in Turtle graphics?

• `forward()`

• `right()`

• `circle()`

• `pendown()`

How can you fill a shape with colour in Turtle graphics?

• Use `begin_fill()` before drawing and `end_fill()` after drawing

• Use `penup()` and `pendown()` around the shape

• Use `forward()` and `right()` to create a filled shape

• Use `circle()` with a colour argument

What is the function of `pendown()` in Turtle graphics?

• To change the direction of the turtle

• To lower the pen so it draws on the canvas

• To stop the turtle from moving

• To fill a shape with colour

Which of the following commands will move the turtle forward by 100 feet?

• `forward(100)`

• `circle(100)`

• `right(100)`

• `penup(100)`

How can you make the turtle turn 90 degrees to the right?

• `right(90)`

• `circle(90)`

• `forward(90)`

• `pendown(90)`

Which of the following is a correct way to use a loop to draw a square in Turtle graphics?

• `for i in range(4): forward(100); right(90)`

• `while i < 4: forward(100); right(90)`

• `if i == 4: forward(100); right(90)`

• `repeat 4: forward(100); right(90)`

What is the result of using `penup()` followed by `pendown()` in a Turtle graphics program?

• The turtle changes colour

• The turtle moves without drawing, then resumes drawing

• The turtle stops moving

• The turtle draws a circle

Which function would you use to create a pattern by repeating shapes in Turtle graphics?

• `circle()`

• `penup()`

• `for` loop

• `right()`

What is the purpose of the `begin_fill()` and `end_fill()` functions in Turtle graphics?

• To change the turtle's speed

• To draw a circle

• To fill a shape with colour

• To move the turtle without drawing
