How to copy specific files from the sub-folders to a new folder in python?

问题

我需要修改代码，只复制每个子文件夹中的最后一个图像（在这种情况下是第7个图像）到一个新文件夹中。

英文:

I have a folder with several sub-folders, each containing the same number of files (here it is 7). The code that I use at the present copies all the files from the different sub-folders within a main folder, to another new folder.

  1. import os
  2. import shutil
  4. src = r'C:\Users\datasets\test
    import os
  5. import shutil
  6. src = r'C:\Users\datasets\test\0'
  7. dest = r'C:\Users\datasets\data_new\test\0'
  8. for path, subdirs, files in os.walk(src):
  9. for name in files:
  10. filename = os.path.join(path, name)
  11. shutil.copy2(filename, dest)
  12. '
  13. dest = r'C:\Users\datasets\data_new\test
    import os
  14. import shutil
  15. src = r'C:\Users\datasets\test\0'
  16. dest = r'C:\Users\datasets\data_new\test\0'
  17. for path, subdirs, files in os.walk(src):
  18. for name in files:
  19. filename = os.path.join(path, name)
  20. shutil.copy2(filename, dest)
  21. '
  23. for path, subdirs, files in os.walk(src):
  24.     for name in files:
  25.         filename = os.path.join(path, name)
  26.         shutil.copy2(filename, dest)

I need to modify the code in a way to copy only the last image (i.e. the 7th image in this case) from each sub-folder (windows file arrangement) to a new folder.

这应该适合您。

  1. import os
  2. import shutil
  3. from glob import glob
  5. src = r'C:\temp\datasets\test
    import os
  6. import shutil
  7. from glob import glob
  9. src = r'C:\temp\datasets\test\0'
  10. dest = r'C:\temp\datasets\data_new\test\0'
  12. for base, dirs, _ in os.walk(src):
  13.     for path in dirs:
  14.         files = sorted(glob(os.path.join(base, path, '*')))
  15.         if len(files) == 0:
  16.             continue
  17.         file = files[-1]
  18.         filename = os.path.join(path, file)
  19.         shutil.copyfile(filename, dest)
  20. '
  21. dest = r'C:\temp\datasets\data_new\test
    import os
  22. import shutil
  23. from glob import glob
  25. src = r'C:\temp\datasets\test\0'
  26. dest = r'C:\temp\datasets\data_new\test\0'
  28. for base, dirs, _ in os.walk(src):
  29.     for path in dirs:
  30.         files = sorted(glob(os.path.join(base, path, '*')))
  31.         if len(files) == 0:
  32.             continue
  33.         file = files[-1]
  34.         filename = os.path.join(path, file)
  35.         shutil.copyfile(filename, dest)
  36. '
  38. for base, dirs, _ in os.walk(src):
  39.     for path in dirs:
  40.         files = sorted(glob(os.path.join(base, path, '*')))
  41.         if len(files) == 0:
  42.             continue
  43.         file = files[-1]
  44.         filename = os.path.join(path, file)
  45.         shutil.copyfile(filename, dest)

  9. dest = r'C:\temp\datasets\data_new\test\0'
  10. for base, dirs, _ in os.walk(src):
  11. for path in dirs:
  12. files = sorted(glob(os.path.join(base, path, '*')))
  13. if len(files) == 0:
  14. continue
  15. file = files[-1]
  16. filename = os.path.join(path, file)
  17. shutil.copyfile(filename, dest)

  25. for path in dirs:
  26. files = sorted(glob(os.path.join(base, path, '*')))
  27. if len(files) == 0:
  28. continue
  29. file = files[-1]
  30. filename = os.path.join(path, file)
  31. shutil.copyfile(filename, dest)
  32. '

  41.         shutil.copyfile(filename, dest)
