[New-bugs-announce] [issue24744] Lack of type checks in pkgutil.walk_packages and friends

[Cal Leeming]

New submission from Cal Leeming:

The documentation states that pkgutil.walk_packages() path must be None or a list of paths [1]. After passing in a string, the result was a blank list rather than a type error or automatic conversion to a list.

If this method is documented that it must only accept a list or None, then there should surely be type checks to this effect? This was a bit of a gotcha that left me head scratching for 30 minutes (after not realising it only took a list, not an str, which in itself seems a bit odd)
