Python — One of python’s top 3 specialties is introspection. Dynamic scripting languages usually excel in this arena.
I believe python/perl offer richer (more comprehensive) introspection and live-debugging than c++/c#/java. The more experienced a programmer gets, the more she is likely to appreciate this feature. However, interviews generally don’t touch on this. Why?
(I guess these may not be well-documented or well known as other features?)
(I guess some interviewers aren’t hardcore.)
Python supports remote debugging too.
