I recommend learning Python. It's a very expressive language with libraries for almost everything. It's used for web development, scientific computing, desktop applications, etc. It's an easy language to learn but also powerful.

Some people here are recommending Ruby. Ruby is also a great language, and probably a little more expressive than Python. However, Ruby lacks libraries for some areas (numerical and scientific computing, machine learning..). Ruby tends to have a more web-focused community.

I would recommend Python.
