Wes, I don't understand what point you are trying to make here. Are you
agreeing with that behaviour? Disagreeing? Thought it was so surprising
that you can't imagine wh

IMO, an os level function such as os.clear_terminal(fd) should only
support terminal/console devices and would be implemented in
Modules/posixmodule.c. Higher-level behavior and support for IDEs
belongs in shutil.

Actually, where in the docs is it clarified which parts of IEEE-754 are
obeyed by Python?
Or where should this be clarified?
To my understanding (according to Wikipedia), IEEE-754 returns +- infinity
for DivideByZeroError and for FloatOverflow.

It's a rare use case; but one use case where th

I'd prefer shutil.clear_screen(). There's already
shutil.get_terminal_size(). I know there's also
os.get_terminal_size(), but its use isn't encouraged.

The shutil module "offers a number of high-level operations on files".
ISTM that shutil.get_terminal_size is a high-level
