  \frametitle{Functions: default arguments}

  \begin{lstlisting}

In []: greet = 'hello world'

In []: greet.split()

Out[]: ['hello', 'world']

In []: line = 'Rossum, Guido, 54, 46, 55'

In []: line.split(',')

Out[]: ['Rossum', ' Guido', ' 54',

                        ' 46', ' 55']

  \frametitle{Functions: Keyword arguments}

We have seen the following

\begin{lstlisting}

legend(['sin(2y)'], loc = 'center')

plot(y, sin(y), 'g', linewidth = 2)

annotate('local max', xy = (1.5, 1))

pie(science.values(), 

            labels = science.keys())

  \end{lstlisting}
