How do you print out blank lines in python?
<p>I haven't been able to find out anything on this.<br>
I would like to know how to use a function (e.g. <code>clear_screen</code>) that can print out 20 blank lines.<br>
The last line of my program should be a call to <code>clear_screen</code>. </p>

<p>The start of my code is:</p>

<pre><code>def new_line():
    print
def three_lines():
    new_line()
    new_line()
    new_line()
def nine_lines():
    three_lines()
    three_lines()
    three_lines()
print " "
nine_lines()
print " "
</code></pre>

<p>The print function works, but not with <code>clear_screen()</code> and that's what I need working.<br>
If anyone can help me or have any suggestions, that would be great, thanks.</p>
