So I'm trying my best to get the indent right everywhere, but sometimes I get the error that the indent is not right somewhere and also I get the error that I use some undefined name n_points; I have even tried typing the whole code into Sage myself, but then if I copy it from there and paste it in the notepad, it still includes all the dots. Even if I delete those dots, Sage still does not get happy when I copy and paste the code after only removing the dots via the notepad.... This is my code
def ell_geom_animation(E,init_points,n_points=10):
var('x,y')
#E = EllipticCurve(y^2==x^3-82*x);
p = init_points
j = len(p)
ell_frames = [plot(E)]*(n_points+j)
point_plots = []
line_plots = []
point_frames = []
line_frames = []
for i in srange(0,j-1):
point_plots += point(p[i][0:2],color='black',size=10)
for i in srange(0,n_points):
p += [E(p[i]+p[i+1])]
point_plots += point(p[j+i][0:2],color='black',size=10)
point_frames.append(point_plots)
line_plots += line([p[i][0:2],p[i+1][0:2]],color='black',size=10)
line_frames.append(line_plots)
A1 = animate(ell_frames)
A2 = animate(point_frames)
A3 = animate(line_frames)
return show(A1+A2+A3) # superimpose frame
Does anyone have some idea what is wrong with the alignments and maybe have a suggestion where I can write my code better such that I can simply copy and paste it in SageMath and press enter. I would very much appreciate suggestions and help.
