Hat Program in Python
Here's an example of the infamous Green Hat program I translate for and run on any calculator that has graphics. I also run this in HPPL but it's a lot faster in Python.
PHP Code:
#cas
def pyhat():
  
t0 ticks # Save the current clock count for timing program
  # Black out background
  
rect_p(0,0,320,240,rgb(0,0,0))
  
# Start program proper
  
p=160q=120
  xp
=144xr=1.5*3.1415927
  yp
=56yr=1zp=64
  xf
=xr/xpyf=yp/yrzf=xr/zp
  
for zi in range(-q,q+1):
    if 
zi>=-zp and zi<=zp:
      
zt=zi*xp/zpzz=zi
      xl
=int(.5+sqrt(xp*xp-zt*zt))
      
# Draw one cross-section of figure
      
for xi in range(-xl,xl+1):
        
xt=sqrt(xi*xi+zt*zt)*xfxx=xi
        yy
=(sin(xt)+.4*sin(3*xt))*yf
        x1
=xx+zz+p
        y1
=yy-zz+q
        pixon_p
(x1,230-y1,rgb(0,255,0))
        if 
y1!=0:
          
Line_p(x1,230-y1+1,x1,230# Erase points below current point
  
ticks-t0
  
# Wait for key and print elapsed time
  
wait
  
print(approx(t/1000)+" seconds")
#end
