[New-bugs-announce] [issue41530] Unhandled exceptions in zoneinfo.ZoneInfo constructor

[Joshua]

New submission from Joshua <josh.ja.butt at gmail.com>:

Attempting to parse specific keys in zoneinfo.ZoneInfo with tzdata installed will raise unhandled exceptions

e.g. on windows

>>> import zoneinfo
>>> zoneinfo.ZoneInfo('Pacific')
PermissionError: [Errno 13] Permission denied: 'C:\\Program Files\\Python39\\lib\\site-packages\\tzdata\\zoneinfo\\Pacific'

>>> import zoneinfo
>>> zoneinfo.ZoneInfo('__init__.py')
ValueError: Invalid TZif file: magic not found

This happens when non TZif files or directories in the tzdata.zoneinfo module are used as keys.
