\subsection*{Targeted exercises} 
\subsubsection*{Exercises for Section \ref{Reading_and_writing_excel_files_using_openpyxl}} 
\begin{enumerate}\setcounter{enumi}{-1}
	\item  Go get the 'Stress-Strain.xlsm' file from our website (\website). 

	\begin{enumerate}
	\item Extract the name of the all the sheets in this file.
	\item Get the value of the cell B3 for the first sheet.
	\item Transpose the results in the first sheet and save the results in a new sheet.
	
	\end{enumerate}
\end{enumerate}
\subsubsection*{Exercises for Section \ref{Specifying_colors_using_the_hexadecimal_standard}} 
\begin{enumerate}\setcounter{enumi}{0}
	\item  Find the colors associated with the logo of a school you have attended or a organization you have worked at and express them in hexadecimal. 

	\item  Change the final code of  Chapter 3 to specify line colors using hexadecimal values rather than  rgb color designations.  Verify the code still works.

	
\end{enumerate}
\subsection*{Comprehensive exercises} 
\begin{enumerate}\setcounter{enumi}{2}
	\item  In this chapter, we saw how to handle results similar to that produced by the final code of Chapter 7. Go back to Chapters 5 and 6. Create a Microsoft Excel file, that has a sheet associated with each chapter. In each sheet, include the data used for the fit (i.e., the experimental $y$-values), the fit $y$ values, and the extracted parameters and their uncertainties. You will likely need to read the openpyxl documentation in order to understand how to create an Excel workbook and add sheets to the workbook. 
    
	\item  Some journals will only accept supplementary information in PDFs or Word documents. This means you cannot simply upload a Microsoft Excel file or a .csv with your data. Write a program that will take the pH titration values from the Excel file used in this chapter, and then convert them to a Microsoft word table. 

\end{enumerate}
