Python L29 Snake Game

What does .penup() do in the snake game?

• Speeds up the turtle

• Stops the turtle from drawing

• Moves the turtle backward

• Changes the color

Why is .tracer(0) used in animation?

• To freeze the screen permanently

• To slow down the turtle

• To allow manual control of screen updates

• To increase loop speed

What does this code do?

• Adds a new segment

• Moves the tail

• Moves the snake’s head forward

• Rotates all segments

s.listen() is required before setting onkey().

• True

• False

The loop for num in range(len(all_body)-1, 0, -1): moves the head forward first.

• True

• False

Match the turtle command to its purpose:

• .goto(x, y)

• Moves turtle without drawing

• .forward(20)

• Moves turtle ahead by 20 pixels

• .penup()

• Moves turtle to specific coordinates

Categorize each item into the correct group:

Groups:

(a) [Screen Setup]

,

(b) [Snake Movement]

• 
• 
• 

To stop the turtle from drawing lines when moving, we use (a)   ().

To update the screen manually after movement, we use ​ (a)   .

• s.update()
• time.sleep()
• import random
• exitonclick()

What is the benefit of using a loop to create the snake body?

• Reduces repetitive code

• Allows random colors for each segment

• Automatically makes the snake faster
