I have difficulties with python.I hope I'm going to learn fast : )

my question is how to do 2D array in python ?

I knew that it's in java as that

a[][]=newdouble[n][m]

but I don't know what is it in python ?

from pylab import* x_start = -200 x_end = 200 y_start = -100 y_end = 100 delta = 10 n = 40 m = 20 xi = 0 for xi in range(0,n+1): xi=x_start+(xi*delta) print "xi",xi yi = 0 for yi in range(0,m+1): yi=y_start+(yi*delta) print "yi",yi

I'm trying to measure side of cube .

the x and y of the top side .

and I collect all the x direction I meant from (-200,200)

and the y form (-100,100)

I want to do 2D array to calculate all the point in the surface " top side "

need your Help !
