\frametitle{Summary}
\label{sec-8}
In this tutorial, we have learnt to –
\begin{itemize}
\item Create lists.
\item Access lists using their index numbers.
\item Append elements to list using the function ``append``.
\item Delete Element from lists by specifying the index number of the
element to be deleted in the ``del`` function.
\item Delete element from list by content using ``remove`` function.
\item Find out the list length using the ``len`` function.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-9}
\begin{enumerate}
\item How do you create an empty list?
\vspace{8pt}
\item Can you have a list inside a list ?
\vspace{8pt}
\item How would you access the end of a list without finding its length?
\end{enumerate}
\end{frame}
\begin{frame}
\frametitle{Solutions}
\label{sec-10}
\begin{enumerate}
\item empty=[]
\vspace{8pt}
\item Yes\\
list\_in\_list=[2.3,[2,4,6],'string,'all datatypes can be there']
\vspace{8pt}
\item Using negative indices\\
nonempty = ['spam', `eggs', 100, 1.234]\\
nonempty[-1]
\end{enumerate}
