需要帮助拼接列表

Question

I have a list of, say, size 144. I need every 16 elements to be stored in a 2-D array. In the end I would want to have a 16x9 2-D array. How do I pull these elements out in a loop and rearrange them? Here is what I have so far...

yuH = np.zeros([N, t])
i = 0
j = 0
for i in range(t):
    for j in range(len(p)):
        print(p[0+j:16+j])
        yuH[:,i] = p[0+j:16+j] # change to N
        j = j + 16

Where N in this case is 16 and t is 9. p is my list of 144. yuH is the matrix I am trying to create. alas it is not working... I get the ValueError "setting an array element with a sequence" at the line yuH[:,i] = p[0+j:16+j] after many runs.

Something like...

p = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20]

p = [[1,  [5,  9,  [13, [17, 
      2,   6,  10,  14,  18, 
      3,   7,  11,  15,  19, 
      4],  8]  12], 16], 20]]

Answer 1

If what you want is just reorganize you array p you can just do this:

import numpy as np

N = 16
t = 9
p = np.arange(t*N) # example array p

yuH = p.reshape([t,N])

print(yuH.shape)

>>> (9, 16)

print(yuH)

>>>
