| 60 | <P> |
| 61 | Actions tell <tt class="module">optparse</tt> what to do when it encounters an option on the |
| 62 | command line. There is a fixed set of actions hard-coded into <tt class="module">optparse</tt>; |
| 63 | adding new actions is an advanced topic covered in section <A HREF="#optparse-extending"><tex2html_cross_ref_visible_mark></A>, Extending <tt class="module">optparse</tt>. |
| 64 | Most actions tell <tt class="module">optparse</tt> to store a value in some variable--for |
| 65 | example, take a string from the command line and store it in an |
| 66 | attribute of <code>options</code>. |
| 67 | |
| 68 | <P> |
| 69 | If you don't specify an option action, <tt class="module">optparse</tt> defaults to <code>store</code>. |
