  \frametitle{About the Session}
  \begin{block}{Goal}
    We shall be covering:
    \begin{itemize}
    \item Conditional statements: if-else
    \item Control flow: Loops
      \begin{itemize}
      \item while
      \item for
      \end{itemize}
    \end{itemize}
  \end{block}
\end{frame}

\begin{frame}
  \frametitle{Python Script}
  \begin{block}{Problem statement}    
    \begin{itemize}
    \item Prompt user for input
    \item Based on input prints:
      \begin{itemize}
      \item 'Be positive' if number is negative
      \item 'Zero' if number is zero
      \item 'Single' if number is one
      \item 'More' if number is greater than one
      \end{itemize}
    \end{itemize}
  \end{block}
\end{frame}

\begin{frame}[fragile]
  \frametitle{\typ{while}}
\begin{block}{Example: Fibonacci series}
  Sum of previous two elements defines the next
\end{block}
\begin{block}{Problem statement}
  Print all Fibonacci numbers less than 10.
\end{block}
\begin{block}{Expected output}
\typ{1 1 2 3 5 8}\\  
\end{block}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Summary}
  \begin{block}{}
    \begin{itemize}
    \item Writing conditional statements
    \item While loops
    \item range function
    \item for and range
    \end{itemize}
  \end{block}
