The patch does not fix it. It becomes like this:
open(...)
Open file and return a stream. Raise IOError upon failure.
It's not just help(open) has problem, help(sqlite3.connect) got it as well:
connect(...)

New submission from Serhiy Storchaka:
Proposed patch adds to locale alias table the mappings for locales supported in
recent glibc (v 2.18). It also modifies the makelocalealias.py script so that
it parses the SUPPORTED file from glibc sources and supports command line
options for source
Serhiy Storchaka added the comment:
Totally added 100 new mappings.

The best fix would be to convert the docstrings to something inspect can parse.
Preferably by converting the functions to use Argument Clinic, though you
could manually mark up the docstring by hand if necessary.

Just wanted to drop in here to let you know that I hit this behaviour recently
when writing a small tool using both configparser and argparse and the
workaround proves rather annoying (custom namespace object or similar).
Would be awesome if this moved

Nick Coghlan added the comment:
The simple patch actually looks like a good way to end up with find_spec
specific bugs because it diverges from the more thoroughly tested main import
path (e.g. it looks to me like it doesn't release the import lock properly)
So the _FoundSpec version actually
Zachary Ware added the comment:
The patch looks good to me (aside from extra whitespace on the blank lines in
methodobject.c, and I agree with Serhiy about s/brackets/parens/). Also, I
like the suggestion of using __text_signature__ instead of '(...)'. However,

Oh sorry, my bad. I messed up. :)
Given that that works, though, why can't open() handle opening /dev/tty
directly in text mode? Clearly, TextIOWrapper can handle the necessary
buffering without the stream having to be seekable.

Antoine already answered that question: it does not make sense to have a single
