[issue16328] win_add2path.py sets wrong user path

Paul Moore added the comment: There's actually a bug in the pre-3.5 script beyond the "does the directory exist" check. The code is if hasattr(site, "USER_SITE"): userpath = site.USER_SITE.replace(appdata, "%APPDATA%") userscripts = os.path.join(userpath, "Scripts") which s

[issue23755] tempfile.NamedTemporaryFile should be able to toggle "delete"

New submission from Stephen Gallagher: Currently, NamedTemporaryFile takes an attribute at initialization that allows it to remove the temporary file on going out of scope or else leave it around. However, it's not possible to change this after the fact. It would be a much more sensible patter
