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

But if shutil.copytree would be able to overwrite, it would be good, and
simetimes enough. And I think it is not too difficult to implement ;-)

yes, something like that ... ;-) but I use windows, and I want the feature
in Python, with a simple and elegant way (1-2 commands)

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

   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?

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

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.

[Python-ideas] Add shutil.ignore_patterns() to shutil.rmtree()

[George Fischhof]

Hi Folks,

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.

BR,
George
