 Python is now the language used in introductory programming courses at a number of top universities \cite{Per11, acmpython}. 
 It is elegant, easy to read and write, portable across platforms, powerful, free and open source, and it has a large scientific computing community. 
 With the appropriate scientific packages installed (NumPy, SciPy, Matplotlib, statsmodels, pandas), Python can easily replicate most MATLAB and R functionality. 
-This means a single language can be used for the entire data collection, processing, and analysis workflow reducing the mental overhead of programming in multiple languages.

 Many of these users have contributed substantial changes to the source code, cataloged issues, or discussed ways of improving the code through GitHub.

 By replacing the awkward Python version of a struct with a simple \texttt{pvlib.location.Location} class we obtained more readable and more functional code.
 Objects of this \texttt{Location} class have added functionality such as more flexible constructors, better timezone handling, and nicer string representations.
 Most importantly, the \texttt{Location} class can be extended by users for their own purposes.
-For example, a user may define her own \texttt{SolarPlant} class that inherits from the \texttt{Location} class, so it can interact with the rest of PVLIB in expected ways, but also has additional user-defined attributes and functionality.
