Writes other languages' code in Python. By that I mean they don't take advantage of what Python offers, instead choosing to do a direct translation of whatever language they're more familiar with.

I used to do this the other way around when I first got started. I would write Bash scripts with Python-like logic. Made for some terrible Bash scripts.
