For this task we want you to scrape live currency exchange rate data from https://uk.finance.yahoo.com/currencies/ as it's requested by a client. This is similar to something you might work on while at Mollybet.

You should make a python3.8 virtual env, and then install the dependencies in requirements.txt

python3 -m venv env
. ./env/bin/activate
pip install -r requirements.txt

Inside yahoo_scraper/__main__.py you'll find a simple server that listens on localhost 8080. Make sure you've activated the env and then start it with:

python -m yahoo_scraper

In another terminal you can connect to it as a client with nc localhost 8080 and send some requests, this is how we will test your solution.

$ nc localhost 8080
Connected!
EUR:USD
0.0
USD:EUR
0.0

Spend 3 to 4 hours filling out the server so that it will scrape the live exchange rate for the requested currency pair and send it back to the client. We're happy for you to use any relatively common python library that you think would help. If you do add it to the requirements.in file and then run:

pip-compile requirements.in > requirements.txt

This task is intentionally open ended, so you are free to structure the code however you want, and make changes to the server if you think it will help. Here are some things that we'll have in mind when judging your solution.

• Correctness: Does the server fetch the correct rate from the yahoo website
• Speed: How long does the client wait for a rate
• Style: Is your code idiomatic python

This is your opportunity to show us what you know and impress us, so don't hesitate to make a change to the server or add parts if you think it would need it.

Once you've written your solution do a small write up of how it works and what changes (if any) you would make before deploying this server to production. After that please zip all the files and send it back to us.
