The document discusses setting up Python development for Android. It describes downloading the Android SDK and creating an Android Virtual Device for testing. The steps include installing SL4A and Python for Android to enable scripting. A simple "Hello World" Python script is run to confirm the environment is working. The document ends with instructions for writing a small greeting script and running it on the virtual device.

Python History CYBER SECURITY INFORMATION TECHNOLOGY CRITICAL INFRASTRUCTURE HOMELAND SECURITY MULTI-USER NETWORK CYBER SECURITY INFORMATION TECHNOLOGY CRITICAL INFRASTRUCTURE From http://en.wikipedia.org/wiki/Python_(programming_language) , Python is an interpreted, general-purpose high-level programming language whose design philosophy emphasizes code readability. The reference implementation of Python (CPython) is free and open source software and has a community-based development model, as do nearly all of its alternative implementations. Python interpreters are available for many operating systems, and Python programs can be packaged into stand-alone executable code for many systems using various tools. Python’s implementation was started in December 1989 by Guido van Rossum in the Netherlands as a successor to the ABD programming language. State of Colorado Office of Cyber Security
