Checklist

• I've added this contribution to the CHANGELOG file.
• I've added my name to the AUTHORS file (or it's already there).
  (Neither of these files seem to exist, so I've done neither of these things.

@shwnchpl The PR looks good.

Would you mind running Black on the code and adding your name to the AUTHORS file?
If you can describe the change in the changelog, I'd appreciate it.

@shwnchpl The PR looks good.

Would you mind running Black on the code...

I can do that.

...and adding your name to the AUTHORS file?

I might be missing something, but I don't see an AUTHORS file anywhere in this repo.

If you can describe the change in the changelog, I'd appreciate it.

Is that changelog.md? I'm not 100% clear on where/how I should add an entry, since I'm not sure what release version this change will be a part of. It also looks like a merge conflict got committed in that file. I can resolve the conflict and describe this change in a way that seems appropriate to me, if that works.

@shwnchpl I am so sorry. I have now fixed the pull request template.

The changelog.md file is now updated with sections for future release. We don't have AUTHORS file anymore.

Thank you for pointing that out. 😞

We don't have AUTHORS file anymore.

Actually, it looks like the mistake was mine. I found the AUTHORS file; it's in the litecli directory. I fixed the style error in dbcommands.py, updated the change log, and added my name to the AUTHORS file.

Sorry about the confusion! 😄

[amjith]

Looks good. Thank you for the PR.

🍨

[shwnchpl]
