ipython doesn't allow creating of classmethods

I tried using ipython to create a class method with the class method decorator. When I press enter I get the following error: enter image description here

I tried using the same decorator in a normal python script and it worked. Why can't I do the same in Ipython?

Solution

  • Upgrade your ipython package to the latest version, e.g.

    $ python3 -m pip install -U ipython

    It works fine for ipython==8.1.0 (released Feb 25, 2022) or later:

    $ ipython
Python 3.11.4 (main, Jun 20 2023, 16:52:35) [Clang 13.0.0 (clang-1300.0.29.30)]

   ...:     @classmethod
   ...:     def test():
   ...:         pass
   ...:

    I could reproduce the issue for the previous version of ipython, 8.0.1:

    $ ipython
