Latest version now converts ftc price to usd/gbp/eur/aud/cad to whole value pennies (0.01), percent price diff now displays correct sign(i.e. up or down), and some timeout errors are handled. Note some server errors may still occur due to an inability to contact the host site for the prices - I am currently trying to work around these but I hope you enjoy this version :D

This isn’t the best script out there and most-likely someone out there has a better way of doing it, but in case others were interest, I wrote this quick python script to get the real time FTC price and convert to fiat currencies.

It’s pretty self explanatory when you look at the code, but basically it looks for the exchange rates via json.load and then compares to the previous iteration. If it’s different it prints the prices in BTC, USD, GBP, EUR, and AUD; as well as trading volumes in FTC and BTC. I’ve attached a screen shot as an example.

code is available here, as well as http://uploaded.net/file/oczk626c

Known Issues:
sometimes the connection times out and you get some red error message about being unable to establish a connection to the api feeds. Just restart the script and all is well. (I need a better solution to this, most-likely some sort of error handling)

For those feeling uneasy about downloading a script from a stranger (I get it, nothing personal) here is the code to copy and paste 8):
