  \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}

  \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}

  \frametitle{Summary}

  \begin{block}{}

    \begin{itemize}

    \item Writing conditional statements

    \item While loops

    \item range function

    \item for and range

    \end{itemize}
