Very simple flask app to perform currency conversion. It has been created just for learning purposes.
This app uses the free and open-source API provided by Exchange Rates API, so there is no need for an api key.
It is recommended, although not mandatory, to use pipenv to install all dependencies, as it comes with a Pipfile.lock file.
pipenv install
pipenv shell
flask runNote: There is no need to export the environment variable FLASK_APP, since it is done automatically (thanks to the python-dotenv package)
