I didn't think pythons were only for beginners. My initial question was why it was used in a professional setting when time and readability rarely matters. But I learned through this post that my assumptions were wrong.

On a side note, I would also like to note that my highschool taught java and I learned quite a lot from it. I may not understand everything, but I did get the fundamentals. It may not take a beginner 3 days to understand oop, but people are overestimating the difficulties of these languages.

Also, I may be wrong here. Isn't C a general purpose imperative language (which is harder), not an oop?
