\frametitle{Objectives}
\label{sec-2}
At the end of this tutorial, you will be able to,
\begin{itemize}
\item Read data from files with a single column of data.
\item Read data from files with multiple columns seperated by
spaces and other delimiters.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Exercise 1}
\label{sec-3}
Read the file \verb~pendulum\_semicolon.txt~ which contains the same data
as \verb~pendulum.txt~ , but the columns are seperated by semi-colons instead
of spaces.Use the IPython help to see how to do this.
\end{frame}
\begin{frame}
\frametitle{Summary}
\label{sec-4}
In this tutorial,we have learnt to-
\begin{itemize}
\item Read data from files, containing a single column of data using the
\verb~loadtxt~ command.
\item Read multiple columns of data, separated by spaces or other
delimiters by adding additional arguments to the \verb~loadtxt~ command.
\end{itemize}
\end{frame}
\begin{frame}
\frametitle{Evaluation}
\label{sec-5}
\begin{enumerate}
\item ``loadtxt`` can read data only from a file with one column only.
True or False?
\item Given a file ``data.txt`` with three columns of data separated by
spaces, read it into 3 separate simple sequences.
\item Given a file ``data.txt`` with three columns of data separated by
``:'', read it into 3 separate simple sequences.
\end{enumerate}
\end{frame}
\begin{frame}
\frametitle{Solutions}
\label{sec-6}
\begin{enumerate}
\item False
\item x = loadtxt(``data.txt'', unpack=True)
\item x = loadtxt(``data.txt'', unpack=True, delimiter='':'')
\end{enumerate}
