Assigning default argument values
<p>Using this script:</p>

<pre><code>color = 'blue'

def say_color(color):
    print 'The color is: ' + color

say_color()
</code></pre>

<p>Here, I am trying to allow <code>say_color</code> to be processed without passing an argument, and the result being the default color (blue). However, if a color is specified, it will not use blue and use the string given instead.</p>

<p>How is this done?</p>
