Question

complete the code to move the ball to the left.
ballposition = (0, 0, 0)
myball = sphere(= ballposition, color = color.green)
for n in range(10):
(1) # number of loops per second
myball.pos.x = myball.pos.x - 1

Explanation:

Step1: Initialize ball position

ballPosition = (0, 0, 0)

Step2: Create the ball object

myBall = sphere(pos=ballPosition, color = color.green)

Step3: Set loop speed (assuming this is a simulation - might be a rate function in relevant library)

rate(1)

Step4: Update x - position to move left

for n in range(10):
myBall.pos.x = myBall.pos.x - 1

Answer:

The completed code with assumptions about the missing parts (assuming a library like vpython where rate is used to control loop speed) is:

from vpython import *
ballPosition = (0, 0, 0)
myBall = sphere(pos=ballPosition, color = color.green)
for n in range(10):
    rate(1)
    myBall.pos.x = myBall.pos.x - 1
