[Python] Add new concept exercise : numbers

[Limm-jk]

Hello, this is our group's first contribution. We've created a new exercise about Concepts 'number'.(#2208)

I worked with OMEGA-Y / Yabby1997 / Ticktakto / wnstj2007

Any guidance is appreciated!

Awesome. Thanks for the PR, it looks great.

Couple of things:

• An object can be added in the file languages\python\config.json under: exercises.concept with the new slug: "currency-exchange" and a new uuid.
• Prettier can be run on each file (.config, .md and .py) before a commit.

That was my comments to help the PR be approved. I will let the maintainers add more comments if necessary.

Overall, this is great! Thank you so much for taking this on, and apologies for the long delay in getting all of you feedback. 😳

I've made some (mostly minor) language suggestions. All of them are suggestions - so you don't have to accept the change if it doesn't make sense, or doesn't "read" well to you.

I've also left a few comments in the test file.

Finally, I'd like to request that you add a task for the student around using the modulus operator and/or calculating remainders. I think % is an important tool in Python, and lends itself well to this currency exchange exercise.

Thank you for reviewing! We will consider your comments and revise it soon :)
