    Good post!

    A few other Python advantages.

    It is an interpreted language. This facilitates trial-and-error exploration of both the language syntax and the CS concepts.

    It supports the major CS concepts (objects, inheritance, lambda) in a natural way.

    It’s useful for both real computational work and small glue/system-task programs.

    It has a rich online community for both classes and Google searching.

    There are other languages that hit some of these buttons, but none seem to put it all together like Python.

      Dear Readers, Pete is a real computer scientist so his endorsement of Python carries a lot more weight than mine.
      Pete, thanks for sharing your thoughts with my readers!

    Thanks a bunch. Seems as though its a “learn as you do” sort of deal. I will definitely try to find an online python course in the near future!

    I promise I’m not a paid shill, but I’ve been very happy with the Treehouse (teamtreehouse.com) Python course. It’s only $9 a month for students, and they also have classes in JavaScript and web frameworks, which are also useful in a GIS career.

    Best of luck!

    I’ve been playing around with http://www.codecademy.com . They have free courses for Python, Java, HTML, and others. It has been pretty helpful for an understanding of how Python works.
