\section{Example of Problem with ShowHide}  

This is a sample problem, which is worth 10 points.

Give the correct python {\tt type} for the following expressions.  Select {\tt noneType} if the expression is illegal.

\begin{itemize}
\item {\tt 3}   \edXabox{expect="int" options="noneType","int","float"}
\item {\tt 5.2} \edXabox{expect="float" options="noneType","int","float"}
\item {\tt 3/2} \edXabox{expect="int" options="noneType","int","float"}
\item {\tt 1+[]} \edXabox{expect="noneType" options="noneType","int","float"}
\end{itemize}

\begin{edXshowhide}{id1}{Hint}
If any of the above answers confuse you, try running the code on your own machine and 
inserting print statements to print out intermediate values of variables so you can examine what 
happens to certain variables - for example, \texttt{guess} - as the program is executed.
\end{edXshowhide}

The showhide hint is generated in the latex file with this code:
\begin{verbatim}
