YES! I've been programming for 55 years, so far, and have never used an IDE except for one year playing with Turbo Pascal and Turbo C. I've always answered questions over on /r/learnpython like this:

    Q: I want to learn python, what IDE should I install?
    A: Why learn both python _and_ an IDE? Just learn python on the commandline.

Though I'm happy in my curmudgeonly rut, it's nice to meet a fellow minimalist aesthete.
