In college, Processing.js was what I used in the Intro to Programming class, which was fun, but like Logo, not powerful enough. Java (why do I have to type so much?) and C (why do I have to worry about memory allocation?) for the intermediate courses. But I never really enjoyed a language until one of my upper division classes had us work in Python.
Finally, a reasonable language. Easy to pick up, but very powerful once mastered. Easy to read, quick and concise to write, thanks to the syntax and interpreter. A massive amount of open sources packages to choose from, for nearly any programming task you can think of. A sane blend of functional, object-oriented, and procedural features.
Python was the language that made me actually enjoy programming. Thanks GVR!
