I get so frustrated coding in Python. I (unsuccessfully) try to restrain myself here, because I like the idea that all languages are great, etc. The truth is that I’ve been using Python on and off for 10 years and it still feels like there’s friction with everything I try to do.

I’m sorry, I don’t want to kick the R vs. Python hornets nest again. This is just my very subjective experience. Actually, even when I use Julia I feel like I can do so much and I get that beginner’s wonder of exploring the language. With Python it’s “KeyError 167”.
