[issue23638] shutil.copytree makedirs exception

[Martin Panter]

Martin Panter added the comment:

In case it’s not clear to others, the first bit of code is from the shutil.copytree() implementation at Lib/shutil.py:303.

The documentation currently says “The destination directory . . . must not already exist”. Yuriy seems to be proposing to make copytree() use the existing destination directory, and only create it if it does not already exist. Perhaps you might be interested in Issue 20849, which proposes passing the os.makedirs(exist_ok=...) flag through, which would allow this functionality in a backwards-compatible way.
