如何使用python获取n维立方体中所有整数点的列表？

给定坐标从(-x,-x,-x,...)到(+ y,+ y + y,...),x,y> 0的立方体,我如何得到所有的列表具有简短易读代码的整数？

到目前为止,我有:

list((x,y,z) for x in range(-x,y) for y in range(-x,y) for z in range(-x,y))
# has the dimension hardcoded

list(itertools.product(*[np.arange(-x, y)]*dim))
# difficult to understand what is going on

list(itertools.product(range(-x, y), repeat=dim))
