This is a basic currency converter built with Python3 that makes use of Flask, Jinja, and the forex-python module.

For user input validation, flash is being used. Helper functions under helpers.py will validate user input for valid currencies (validated against the API valid currencies), and amount.

Doctests were written for the helper functions. Unit tests were also written and are part of this project (please refer to tests.py file).

Users will be presented with the home page of the website and FROM and TO currency entries are expected, as well as the amount to be converted. The list of supported currencies can be found here. Once user input validation is completed (and passed), the conversion takes place and a screen with the conversion results is rendered, with the option to start a new conversion.
