I have a task to synchronize folders but some files should be remained untouched. I think this is a very common task.

I found that shutil.copytree() has ignore_patterns() but rmtree() has not.

So here comes my idea: add ignore_patterns() to rmtree() it is a good feature and makes the functions symmetric.

You can't remove a tree when remain its branches. Thus rmtree() with ignore_patterns will always fail.

For your particular case I suggest to use os.walk(). You can implement arbitrary application specific conditions.

If the remaining equals to ignore_pattern plus the container folders, then it is succesful ;-) In my opinion

Synchronize folders using rmtree()? I don't get it.

I think it is not that common.

rmtree() is like ``rm -r``, not like ``find . -name *.pyc -delete``.

Why impose artificial symmetry?

Actually it would be good if copytree() would be able to overwrite files and directories. George

yes, something like that ... ;-) but I use windows, and I want the feature in Python, with a simple and elegant way (1-2 commands) 2017-05-05 16:14 GMT+02:00 Oleg Broytman :

Seems you want rsync, no?

I can understand the need but I don't think such a library/script should be in stdlib.

And I think it is not too difficult to implement ;-)
