I used to be gung-ho about convincing economists to use Python (started econpy.org in the 1st year of my PhD in economics, stopped updating it after 2 years). But now I just don't care. The vast majority of economists are horrible programmers, however most know how to script in at least 1 language, and a small number of them are actually really good at scripting. An extremely small number of economists know they're way around at least 1 entire general purpose programming language.

It seems that every time this gets brought up online a sea of infamous Fortran-programming-economists always tell you how fast Fortran is compared to everything else, signing it with "Fortran or GTFO". I've met hundreds/thousands of economists and econ grad students at schools ranked from 1 to 200, and I don't recall a single one that actually used Fortran (I'm sure there is a non-zero quantity -- I probably just haven't cared to talk with them b/c they are most likely macro theorists).

The fact of the matter is that in economics graduate school, your professors could care less what language you use. It isn't an algorithm competition, it's a story telling competition. But the type of story telling economists do is no less noble than writing elegant algos. Writing a story based on economic mechanisms and behaviors and supporting it with quality data, sound statistics, and logical/exact theories is no simple task.
