gh-92244 Added clear() to clear the interpreter shell in case it is a bit clunky

[ghost]

this change added will clear the terminal in case it is a bit clunky and full of errors,
previously while trying to clear the terminal shell there would be an error as follows:

Python 3.10.4 (main, Apr  2 2022, 09:04:19) [GCC 11.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> clear()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'clear' is not defined

with this change the clear() command will clear the terminal shell

As a simple workaround you can define a global function in your interactive startup file.
This will also avoid having to load the builtin for non-interactive sessions and needing to manage cross compatibility.

well i think of the python interactive shell should have it built in , because atleast for me when i switch to different workspaces its kinda tedious to set the pythonrc everytime

Hi, welcome to CPython! An addition to builtins or sitebuiltins needs to meet quite a high bar to be accepted, and I'm not sure if this meets that bar. Regardless, a new feature like this is very unlikely to get accepted without being first discussed in an issue, so I'd definitely recommend opening one. If you do so, and update the title of this PR to gh-XXXXX: Added clear() to clear the interpreter shell, where XXXXX is the ID of the issue you've opened, then the relevant CI check will go green.
