New submission from Danny Lin <[email protected]>:
On Linux (tested on Ubuntu 16.04), if "/path/to/file" is an existing file, the
code:
open('/path/to/file/somename.txt')
raises NotADirectoryError: [Errno 20] Not a directory:
'/path/to/file/somename.txt'
On Windows, similar code:
open(r'C:\path\to\file\somename.txt')
raises FileNotFoundError: [Errno 2] No such file or directory:
'C:\\path\\chrome\\to\\file\\somename.txt'
I think the behavior on Linux is not correct. The user probably cares about the
existence of the file to be opened, rather than whether its ancestor
directories are valid.
OTOH, if NotADirectoryError should be raised, it should mention '/path/to/file'
rather then '/path/to/file/somename.txt'. But what if '/path/to' or '/path' is
actually a file? Should it be '/path/to' or '/path' instead for the same reason?
