Please Help: Issue with 3D

Processing.py
5

Hello, so this is the code I have. But the issue is, even when I used the references on the processing website, I still get the same result, and I’m not sure why

def setup(): 
    size(800, 600, P3D)
    translate(400, 300)
    sphere(100)
    
    lights()
    
    background('#004477')
    
    pushMatrix()
    translate(600,300)
    sphere(100)
    popMatrix()
    
    pushMatrix()
    translate(200,300)

    popMatrix()
