python - How do I create an array of 3D coordinates in Python?

Question

I was wondering what would be an efficient way to create an array of coordinates of a 3d space. For example:

[ [x,y,z] ,for x in range(1000) for y in range(1000) for z in range(1000) ]

will take allot of time.

您可以使用 Numpy 和 mgrid 函数：https ://docs.scipy.org/doc/numpy/reference/generated/numpy.mgrid.html

但主要问题是您分配了大量内存，这总是很慢。也许您可以编写具有较小分辨率的程序并一次执行 10 步？
