I'm not calling you a liar, I'm just pointing out that saying "I have
done this" is not a use-case. You must have had a reason for *why* you
did it, beyond just "because I can!" (or in this case, "because I can't,
so I used a list instead").
It's the *why* that's important.
When we ask for use-cases, the implication is that contrived examples
don't really count:
- to win a bet
- just out of curiosity, to see if it can be done (I've done this)
- to write obfuscated code
- to solve an exercise:
"Exercise 7: choose a random key:value pair from
a dict, and print the result."
etc. So *on its own* the ability to choose a random key:value pair from
a dict is not very compelling. If it were combined with a *why* then it
could become a stronger example, presuming of course that this use-case
would not be equally well served by listifying the key:value pairs
first.
As I said, perhaps I just lack imagination.
