In this tutorial, we have learnt to –
\begin{itemize}
\item Open and close files using the ``open`` and ``close`` functions respectively.
\item Read the data in the files as a whole,by using the ``read`` function.
\item Read the data in the files line by line by iterating over the file object
using the ``for`` loop.
\item Append the lines of a file to a list using the ``append`` function within
the ``for`` loop.
\end{itemize}

\begin{itemize}
\item Displays the data as strings,all in a line
\item Displays the data line by line as strings
\item Displays the data line by line but not as strings
\end{itemize}
\end{enumerate}
