Put the following in `a.py`: ``` #!/bin/python3 try: while True: pass except KeyboardInterrupt: pass ``` Run with `python a.py`: ``` $ python a.py ``` Press `Ctrl+C` to interrupt it: ``` ^CTraceback (most recent call last): File "/tmp/a.py", line 3, in <module> while True: pass KeyboardInterrupt ``` Why is the error still printed and not captured? Python version: Python 3.11.3, on Linux.
