Line 626:
print "Welcome to the cheese shop!"
print "Can I interest you in some choice gouda?"
</pre>
====even more choices: <code>elif</code>====
If you have more than two cases, you can use the <code>elif</code> keyword to check more cases. You can have as many <code>elif</code> cases as you want; Python will go down the code checking each <code>elif</code> condition until it finds a true condition or reaches the default <code>else</code> block.
<pre>
sister_age = 15
brother_age = 12
if sister_age > brother_age:
print "sister is older"
elif sister_age == brother_age:
print "sister and brother are the same age"
else:
print "brother is older"
</pre>
You don't have to have an <code>else</code> block, if you don't need it:
<pre>
color = "orange"
if color == "green" or color == "red":
print "Christmas color!"
elif color == "black" or color == "orange":
print "Halloween color!"
elif color == "pink":
print "Valentine's Day color!"
</pre>
