'list indices must be integers, not tuple' error in newbie script

Hi expers!!

Im a new user of SAGE. Right now im writing a script that plot 'N' random lines of lenght=1 in a rectangle of b*h center in axes. The code is shhow below:

N=float(raw_input('Número de rectas aleatóreos (N)?:\n')) b=float(raw_input('Base del rectángulo (b>1)?:\n')) h=float(raw_input('Altura del cuadrado (h>1)?:\n'))

uniforme_x=RealDistribution('uniform',[-b/2,b/2]) uniforme_y=RealDistribution('uniform',[-h/2,h/2])

lista_x=[uniforme_x.get_random_element() for j in srange(N)] lista_y=[uniforme_y.get_random_element() for j in srange(N)]

lista_xy = zip(lista_x , lista_y)

lineas=[]

d2=112

for j in lista_xy: x1 = lista_xy[j][0] y1 = lista_xy[j][1] while d2>11: x2 = uniforme_x.get_random_element() y2 = uniforme_x.get_random_element() d2=(x1-x2)(x1-x2)+(y1-y2)*(y1-y2) lineas.append(line([lista_xy[j],(x2,y2)]))

grafico=sum(lineas)

grafico.show()

When i execute this code I get the error messege 'list indices must be integers, not tuple'.

Whats the problem?

Waiting for your answers.

Thanks a lot!
