[issue18163] Add a 'key' attribute to KeyError

[Orian Zinger]

Orian Zinger  added the comment:

Hi all,

As a Python developer, I encountered lots of blurry exception messages in the 
product logs such as:
   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.
