<p>Segments of strings can be cut out by using square brackets to slice the string: </p><p> <tt class="ttfamily">pyxplot> <b class="bfseries">poem = "On the last sabbath day of 1879<img src="images/img-0038.png" alt="$\backslash $" style="vertical-align:-5px;

If two colon-separated numbers are specified, <tt class="tt">[x:y]</tt>, then the substring from character position <tt class="tt">x</tt> up to but not including <tt class="tt">y</tt> is returned. If either <tt class="tt">x</tt> or <tt class="tt">y</tt> are omitted, then the start or end of the string is used respectively. If either number of negative, then it counts from the end of the string, <img src="images/img-0156.png" alt="$-1$" style="vertical-align:0px;
width:21px;
height:12px" class="math gen" /> being the last character in the string. </p></div>
