[issue24920] shutil.get_terminal_size throws AttributeError

[Isaac Levy]

Isaac Levy added the comment:

I guess users need to check standard streams for None. There's not many uses of 
stream attributes in core libs.

Maybe catch should be Exception -- since it's documented to return a fallback 
on error.
