Question

•what are 3 dimensional array? how we can access the elements from 3d array and how to assign the value of aaray
《 answer according to c language 》​

Answer 1

We will encounter arrays of varying dimensionalities:

# A 0-D array

np.array(8)

# A 1-D array, shape-(3,)

np.array([2.3, 0.1, -9.1])

# A 2-D array, shape-(3, 2)

np.array([[93, 95],

[84, 100],

[99, 87]])

# A 3-D array, shape-(2, 2, 2)

np.array([[[0, 1],

[2, 3]],

[[4, 5],

[6, 7]]])

Similar to Python’s sequences, we use 0-based indices and slicing to access the content of an array. However, we must specify an index/slice for each dimension of an array:

>>> import numpy as np

# A 3-D array

>>> x = np.array([[[0, 1],

... [2, 3]],

...

... [[4, 5],

... [6, 7]]])

# get: sheet-0, both rows, flip order of columns

>>> x[0, :, ::-1]

array([[1, 0],

[3, 2]])

One-dimensional Arrays

Let’s begin our discussion by constructing a simple ND-array containing three floating-point numbers.
