\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}
