python - 如何对相关的 .tif 文件进行分组？

Question

我正在尝试对与 .tif 图像关联的相关文件进行分组。从列表中可以看到，每组有 7 个相关文件。我正在寻找一种对这些文件进行分组的方法，以便我可以通过 shutil.move() 将它们移动到各个文件夹中。

以下脚本是我根据 this answer 尝试失败的脚本。结果与输入 files 列表相同。

我如何调整它来执行我想要的分组？

import os, itertools

files = ['F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tfw',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.aux.xml',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.ovr',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.vat.cpg',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.vat.dbf',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.xml',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tfw',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.aux.xml',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.ovr',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.vat.cpg',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.vat.dbf',
       'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.xml']

test = sorted(files)
grouped = [list(g) for _, g in itertools.groupby(test, lambda x: x.split('_')[1])]

<小时/>

预期输出:

[['F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tfw',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.aux.xml',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.ovr',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.vat.cpg',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.vat.dbf',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511759_sw.tif.xml'],
           ['F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tfw',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.aux.xml',

           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.vat.cpg',
           'F:\\juniper_project\\data\\raster\\deliverables\\OR\\reclass\\reclass_4511760_sw.tif.vat.dbf',

Answer 1

关闭!分割列表上的索引是一次性的，应该是2。

尝试

grouped = [list(g) for _, g in itertools.groupby(test, lambda x: x.split('_')[2])]
