-\frametitle{Running Python script from command line}
-\label{sec-2}
-
-\begin{itemize}
-\item Create a script, open text editor and type the following
-\begin{verbatim}
-     print "hello world!"
-     print
-\end{verbatim}
-
-\item Save the script as \texttt{hello.py}

-\frametitle{Better way of fixing}
-\label{sec-7}
-
-\begin{verbatim}
-   from scipy import linspace
-\end{verbatim}
-
-  instead of
-\begin{verbatim}
-   from scipy import *
-\end{verbatim}
-
-    \texttt{*} means import all functions from name-space \texttt{scipy}.

-\label{sec-8}
-
-\begin{verbatim}
-    from scipy import linspace, pi, sin
-    from pylab import plot, legend, annotate
-    from pylab import xlim, ylim, title, show
-\end{verbatim}
-
-  Is better than, \texttt{from scipy import *} \& \texttt{from pylab import *}.

-\frametitle{Another Fix}
-\label{sec-9}
-
-\begin{verbatim}
-import scipy
-import pylab
-x = scipy.linspace(-5*scipy.pi, 5*scipy.pi, 500)
-pylab.plot(x, x, 'b')
-pylab.plot(x, -x, 'b')
-pylab.plot(x, scipy.sin(x), 'g', linewidth=2)
-pylab.plot(x, x*scipy.sin(x), 'r', linewidth=3)

-\frametitle{Exercise 1}
-\label{sec-10}
-

-    $-2\Pi$
-  to 
-    $2\Pi$
-  .

-\frametitle{What is a module?}
-\label{sec-11}
-
-  Module is simply a file containing Python definitions and
-  statements. Definitions from a module can be imported into other
-  modules or into the main module.

-\frametitle{Python standard library}
-\label{sec-12}
-
-  Python has a very rich standard library of modules.
-\begin{itemize}
-\item Few libraries
-
-\begin{itemize}
-\item Math: \texttt{math}, \texttt{random}
-\item Internet access: \texttt{urllib2}, \texttt{smtplib}
-\item System, Command line arguments: \texttt{sys}
-\item Operating system interface: \texttt{os}
-\item regular expressions: \texttt{re}
-\item compression: \texttt{gzip}, \texttt{zipfile}, \texttt{tarfile}
-\end{itemize}
-
-\item More information
-
-\begin{itemize}
-\item \href{http://docs.python.org/library}{http://docs.python.org/library}
