解决方案
It's possible that your os.chdir
is confusing os.walk
. Try restoring the working directory before the next iteration.
Better yet, you can use a with
statement if you define a context manager for chdir. Here's an example, which defines a version of chdir
that you can use as follows:
for root, dirs, files in os.walk(RootDirectory, topdown=False): for directory in dirs: currentPath=os.path.join(root,directory) with chdir(currentPath): # now inside the specified directory # after exiting 'with', original directory will be restored
