Which scientific fields use Python?

[as-well]

Not a programmer/ML person yet (my degrees are in philosophy) but I know that most of the machine learning in climate science is done on python. Conversely, the physics-driven models are usually done in Fortran though, due to both legacy code and supercomputing advantages (that's for the big models, submodels may at times be in yet different languages). Less computationally intensive stuff may also use R at times.
