====more choices: <code>if</code> and <code>else</code>====

'''<code>if</code>''' lets you execute some code only if a condition is <code>True</code>. What if you want to execute different code if a condition is <code>False</code>?

Use the '''<code>else</code>''' keyword, together with <code>if</code>, to execute different code when the <code>if</code> condition isn't <code>True</code>. Try this:

<pre>
sister_age = 15
brother_age = 12
if sister_age > brother_age:
    print("sister is older")
else:
    print("brother is older")
</pre>

Like with <code>if</code>, the code block under the <code>else</code> condition must be indented so Python knows that it is a part of the <code>else</code> block.
