如何将用户输入的 8 个数字列表拆分为四等分

Question

Currently, I have data = input('Please input 8 numbers \n') What I want to do is split this list into quarters so I may input them into matrices A and B of a 2x2 format

Answer 1

Yeah, for that, you can do

data = input('Please input 8 numbers \n')
quarters = []
split_input = data.split(" ")
for i in range(0, len(split_input), 2):
    quarters.append([split_input[i], split_input[i+1]])

print(quarters)

Please input 8 numbers 
1 2 3 4 5 6 7 8
[['1', '2'], ['3', '4'], ['5', '6'], ['7', '8']]

Answer 2

Depending on the order in which the input should be stored in A, B:

import numpy as np

split_input = input('Please input 8 numbers \n').split(" ")
A, B = np.array(split_input, dtype='float').reshape(2, 2, 2)

print(A)
print(B)

Please input 8 numbers 
1 2 3 4 5 6 7 8
[[1. 2.]
 [3. 4.]]
[[5. 6.]
 [7. 8.]]

or

arr = np.array(split_input, dtype='float').reshape(2, 2, 2)
A, B = np.swapaxes(arr, 0, 1)

print(A)
print(B)

[[1. 2.]
 [5. 6.]]
[[3. 4.]
 [7. 8.]]

or

arr = np.array(split_input, dtype='float').reshape(2, 2, 2)
A, B = np.swapaxes(arr, 1, 2)

print(A)
print(B)

[[1. 3.]
 [2. 4.]]
[[5. 7.]
 [6. 8.]]

etc.

Answer 3

separated with ,

import numpy as np

_input = input('Please input 8 numbers \n')
int_input = [int(x) for x in _input.split(',')]
x = np.array(int_input).reshape(2, 2, 2)
