>>> import io >>> d = io.open('.') Traceback (most recent call last): File "", line 1, in IsADirectoryError: [Errno 21] Is a directory: '.' >>> >>> import os >>> d = io.open(os.open('.',0)) >>> d <_io.TextIOWrapper name=3 mode='r' encoding='UTF-8'> >>>

io.open() clearly doesn't care about opening directories as long as they are passed as os.open() file descriptors. Quite unexpected!

Good catch indeed.

Note that attempting subsequent operations on the returned object do raise IsADirectoryError. >>> import io >>> import os >>> d = io.open(os.open('.',0)) >>> d.read() Traceback (most recent call last): File "", line 1, in IsADirectoryError: [Errno 21] Is a directory >>>
