我們用python建立檔案的時候需要按照一定的序號將檔案放入規定的資料夾，建立資料夾的時候需要用到索引 i，j，k 等，以下是我寫好的程式碼

import os
import numpy as np
from matplotlib import pyplot as plt
import time
path = 'G://phase8//original_npy1//'
# new_path = 'G://phase8//phs1//'
for root, dirs, files in os.walk(path):

    for i in range(len(files)):

        file_path =
 
 os.path.join(root, files[i])
        phase = np.load(file_path)
        for j in range(20):
            new_path = 'G://phase8//phs1//'
            if i < 10:
                new_path = new_path + str('000') + str(i) + '_' + str(j)

            if i >= 10 and i < 100:
                new_path = new_path +
 
 str('00') + str(i) + '_' + str(j)

            if i >= 100 and i < 1000:
                new_path = new_path + str('0') + str(i) + '_' + str(j)

            if i >= 1000:
                new_path = new_path + str(i) + '_' + str(j)

            os.makedirs(new_path)

            phase1 = phase[256*j: 256
 
*j+256,:]  # 長橫圖

            for k in range(40):

                phase2 = phase1[:, k*128:256+k*128]  # 256*256的圖片 間隔為128
                plt.imshow(phase2)
                plt.axis('off')
                plt.gcf().set_size_inches(256 / 100, 256 / 100)
                plt.gca().xaxis.set_major_locator(plt.NullLocator())
                plt.gca().yaxis.set_major_locator(plt.NullLocator())
                plt.subplots_adjust(top=1,bottom=0,right=1,left=0,hspace=0,wspace=0)
                plt.margins(0, 0)

                if i < 10:
                    # np.save(new_path + '//' + str('000') + str(i) + str('_') + str(j) + str('_') + str(k), phase2)
                    plt.savefig(new_path + '//' + str('000') + str(i) + str('_') + str(j) + str('_') + str(k), dpi=100)
                if i >= 10 and i < 100:
                    # np.save(new_path + '//' + str('00') + str(i) + str('_')+str(j) + str('_') + str(k), phase2)
                    plt.savefig(new_path + '//' + str('00') + str(i) + str('_') + str(j) + str('_') + str(k), dpi=100)
                if i >= 100 and i < 1000:
                    # np.save(new_path + '//' + str('0') + str(i) + str('_')+str(j) + str('_') + str(k), phase2)
                    plt.savefig(new_path + '//' + str('0') + str(i) + str('_') + str(j) + str('_') + str(k), dpi=100)
                if i >= 1000:
                    # np.save(new_path + '//' + str(i) + str('_')+str(j) + str('_') + str(k), phase2)
                    plt.savefig(new_path + '//' + str(i) + str('_') + str(j) + str('_') + str(k), dpi=100)

                print(i, j, k)

print('---save successfully---')
