 \subsection{IDEs and Python}
 
+An integrated development environment (IDE) is an application that enables you to write code, debug code, and often compile it and execute it. On Linux systems, Python typically comes bundled with IDLE, although others are available. \cite{programiz:ides}\cite{realpython:ide}
+
+The broader question ``should you use an IDE?'' is not as easy to answer. There are reasons IDEs exist, and if you are working on a large project, they can help to speed up the process. However, when you are first starting with Python, it is probably going to be more enlightening to you to use Python directly from the command line, as you will have a better feel for what Python is doing behind the scenes when you eventually do move over to an IDE. (See the section ``\nameref{exec-python}'' below.)

 \subsection{Version 2 versus Version 3}
 
 The initial version of Python 2 was released in 2000. Python 2.7, which was released in 2010, is the last version of Python 2. Many people continue to use Python 2, but they shouldn't, and neither should you.
