Currency converter GUI with principles

MK's solution to assignment 5.

Info

The whole solution is sensibly split into distinct components, each expressed as a seprate file in src module. There are seperate files for creating GUI layout, downloading currency data or loading it from previously saved file.

There are no strange functions that modify the class attributes from outside of it, no references to some global variables.

Running app

To run the application, follow some good principles and first create virtual env:

uv venv venv

or in a more standard way (if you don't have uv installed):

python -m venv venv

Next activate the environment and install the required packages:

uv pip intall -r requirements.txt

or if you prefer it slow:

pip install -r requirements.txt

Finally type:

python main.py
