Byte Trading Coding Test

General Comments

• I have worked on this little project in my free time, around quite a busy work schedule.

• I have deliberately tried to focus on code readability, as opposed to optimisation ("premature optimisation is the root of all evil").

Installation

I have chosen to use poetry and pyenv. To setup and use the environment:

poetry install
poetry shell

This will automatically create a virtual environment and install the required dependencies.

Usage

python main.py

The script will connect to Binance and periodically print the top bid/ask prices for BTCUSDT.

Development

Pre-commit Checks

To run them manually:

pre-commit run --all-files

This will run a series of linting and type-checking (flake8, black, mypy) and tell you what needs to be fixed. You may need to run it more than once. It will be automatically run when attempting to commit a change.

Testing

To run tests:

pytest

For test coverage:

pytest --cov=keypad tests/
