  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}
