I don't know about too many others in the bioinformatics field, but I reckon I write about 80% of my code in Python and 20% in R. R for stats and plotting; Python for wrangling data. Having said that, they're the languages I learned in my studies (along with java) and I haven't had the time and motivation to move beyond them since.
