I want to share with you an early version Currex, a Pythonic currency calculator that makes working with currencies and exchange rates simple and smoots.

I often use Python as a command-line calculator. Yet, I need to go back to Google Search to convert between currencies. So, for my own convenience, I created this library that makes it easy to add, multiply and change currencies. One of the core features is autocasting - when using a few currencies, automatically convert them to the first one.

It is intended to be used in interactive Python sessions (such as Jupyter Notebook, IPython, etc.) to get ballpark estimates of prices - e.g. when traveling, buying online, etc. Personally, I use it from the command line IPython.

It is a new package, so I'm open to suggestions.

It is NOT intended to be used in production code. Every API design decision I made was to make it as simple as possible to use in interactive sessions. Some of them are consciously at odds with a tool that could be used in a library.

EVEN MORE IMPORTANT: Never use it for any important decisions - taxes, investments, etc. There is no guarantee that the exchange rates are up-to-date and correct. Note that even major players make mistakes, e.g. a Google glitch from the last year (https://www.barrons.com/news/google-glitch-undervalues-polan...). Always use the official exchange rates.
