我的numpy数组总是以零结尾？(My numpy array always ends in zero?)

 我想我错过了某个地方。 我使用两个for循环（x和y）和一个基于x，y位置的函数填充了一个numpy数组。 唯一的问题是，无论数组的大小如何，数组的值总是以零结尾。 
 
thetamap = numpy.zeros(36, dtype=float)
thetamap.shape = (6, 6)
for y in range(0,5):
    for x in range(0,5):
        thetamap[x][y] =  x+y
print thetamap

I think I missed something somewhere. I filled a numpy array using two for loops (x and y) and a function based on the x,y position. The only problem is that the value of the array always ends in zero irregardless of the size of the array. 
 
thetamap = numpy.zeros(36, dtype=float)
thetamap.shape = (6, 6)
for y in range(0,5):
    for x in range(0,5):
        thetamap[x][y] =  x+y
print thetamap
