[New-bugs-announce] [issue42177] Improving KeyError exception

[Orian Zinger]

New submission from Orian Zinger <zinger777 at gmail.com>:

Hi all,

As a Python developer, I encountered lots of blurry exception messages in the product logs such as:
<time and date> <process name> <log severity> Failed to do something. Exception: 'some key'

I believe printing the key name without explaining the exception itself is bad (explicit is better than implicit).

Thus, after forking the repository, I added a short explanation about the Exception.
Now, it looks like:

>>> try:
...     {}['some key']
... except Exception as e:
...     print(e)
... 
Missing key: some key

I'm a newbie in a contribution to CPython, so please let me know if the idea behind my commit is good. If not, please explain how can I improve my commit so it'll be pulled later to the main branch.

Regards,
Orian.
