New submission from Atsuo Ishimoto <[email protected]>:
I sometime use a hack to start interactive console after running script.
.. code-block:: python
import os
os.environ['PYTHONINSPECT'] = 'x'
print("Hello")
This hack works because ``PYTHONINSPECT`` is checked `here
<https://github.com/python/cpython/blob/master/Modules/main.c#L738>`__ when
exiting Python.
However, if the script uses ``sys.exit()`` to exit from Python, interactive
console doen't apper because unhandled ``SystemExit`` exception leads
``exit()`` call to kill process, without checking ``PYTHONINSPECT``.
.. code-block:: python
import os, sys
os.environ['PYTHONINSPECT'] = 'x'
print("Hello")
sys.exit(1) # Interactive console will not start
I think feature to allow updating ``Py_InspectFlag`` is useful, and this is a
bugs to be fixed. However, setting environment variable to start console is not
intuituve.
So instead of fixing bug, I would like to propose a small function to set
``Py_InspectFlag`` to start interactive console after running script.
.. code-block:: python
sys.setinteractiveflag(bool)
Thoughts?
