<hr>
<h2>描述</h2>
<p>Python rindex() 返回子字符串 str 在字符串中最后出现的位置，如果没有匹配的字符串会报异常，你可以指定可选参数[beg:end]设置查找的区间。</p>
<h2>语法</h2>
<p>rindex()方法语法：</p>
<pre>
str.rindex(str, beg=0 end=len(string))
</pre>
<h2>参数</h2>
<ul>
<li>str -- 查找的字符串</li>
<li>beg -- 开始查找的位置，默认为0</li>
<li>end -- 结束查找位置，默认为字符串的长度。</li>
</ul>
<h2>返回值</h2>
<p>返回子字符串 str 在字符串中最后出现的位置，如果没有匹配的字符串会报异常。</p>
<h2>实例</h2>
<p>以下实例展示了rindex()函数的使用方法：</p>
<pre>
#!/usr/bin/python
str1 = "this is string example....wow!!!";
str2 = "is";
print str1.rindex(str2);
print str1.index(str2);
</pre>
<p>以上实例输出结果如下：</p>
