-\begin{itemize}
-\item What software Testing is?
-\item Learn to test simple functions for their functionality.
-\item Learn how to automate tests.
-\item Need for coding style and some of the standards followed by the Python Community.
-\item Handling Errors and Exceptions.

-\begin{verbatim}
-def gcd(a, b):
-      if a % b == 0: 
-          return b
-      return gcd(b, a%b)
-\end{verbatim}

-    if b == 0:
-        return a
-    return gcd(b, a%b)
