Python
The canonical, "Python is a great first language", elicited, "Python is a great last language!"
I remember my first encounter with Python was in 2004 while my cousin was asking me for programming help, and I disregarded Python (to my regret!) as a toy language. I told him that he should focus on a real language like C, C++, or Java. I humbly bite back my tongue and now realize the power of the open source community with Python.
I believe Python has really democratized programming is the best general purpose language out there! I cover interesting functionality or avant-garde new packages in Python.
