ascii_art fail in jupyter notebook

[Jianping Pan]

SageMath version 9.7.beta1, Release Date: 2022-05-26

Operating system: macOS Monterey 12.4

When running sage in Jupyter notebook, I get the following problem.

sage: ascii_art(list(Partitions(5)))

<repr(<sage.typeset.ascii_art.AsciiArt at 0x7f8f358aa250>) failed: OSError: [Errno 25] Inappropriate ioctl for device>

The exact same code works when I run my sage in the terminal. My guess is the "_terminal_width()" private method does not work with Jupiter. In the terminal, the following command gives

sage: ascii_art(list(Partitions(5)))._terminal_width()

80

While in Jupiter notebook I get 

OSError: [Errno 25] Inappropriate ioctl for device 

This was not an issue before I recently upgraded my sage.

Thanks!

The above error can be fixed by setting

sage: sage.typeset.ascii_art.AsciiArt._terminal_width = lambda x: 80

(80 or any other width you want)
