I asked this question before on Stackoverflow, but it was closed as off-topic, so will try again here.
I'm writing a scientific article and a dissertation in biology, for which I used Python for simulations. Some people in our department, especially the "non-computer-people", don't know what Python is, so I want to reference something helpful. Open-Source scientific tools such as CellProfiler usually tell you how to reference them, but Python doesn't.
How is the Python language properly referenced? Are there any articles in journals available I could link to?
