JSON is a very common data format, but reading it can be a little difficult, especially if the JSON contains very little white space. If you have Python 2.6 or above you have use the json.tool to format the JSON so that you can read it correctly.

To stop code execution in Python you first need to import the sys object. After this you can then call the exit() method to stop the program running. It is the most reliable, cross-platform way of stopping code execution. Here is a simple example.
