+  \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}

+  \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}
