a list as a relationship between indices and
elements. This relationship is called a <b>mapping</b>; each index
"maps to" one of the elements. <br />

List indices work the same way as string indices:
</font><ul><li><font color="black">Any integer expression can be used as an index.</font><br />
<br />
</li><li><font color="black">If you try to read or write an element that does not exist, you
get an <tt>IndexError</tt>.</font><br />
