Good question. Python is one software (among others) that is somewhat reliable, both based on personal experience over several years, as well as according to the Coverity study (some years ago, IIRC). Interesting that at least some replies have some items in common. I also have to say the same, at least about vim and vi before it - hardly ever (or never) crashed on me, IIRC. Linux of course, does crash once in a while, but again, very rarely, much less than Windows, IME. Same for Unixes I used before Linux - okay, not all the same. Some of the PC Unixes used to crash more than once in a blue moon. HP-UX - very reliable software, when I used it in production for some years. Even their patch management system was very good, and helped with the reliability.
