Revision 6. </p> <p>I am process A and I own object Obj. Now I decide to fork(): process B is born.</p> <p>How do I do to make process B call the methods of A's object Obj (and not the methods of its own copy of Obj...) ?</p> <p>This is what this module does: you create the "CallPipe" for Obj prior to fork()ing, and then process B can call any method of A's object Obj through it.</p> Parse call function for Py2.6 and Py2.7 (Python) 2009-02-28T20:13:15-08:00Jervis Whitley <p style="color: grey"> Python recipe 576671 by <a href="/recipes/users/4169341/">Jervis Whitley</a> (<a href="/recipes/tags/ast/">ast</a>, <a href="/recipes/tags/call/">call</a>, <a href="/recipes/tags/function/">function</a>, <a href="/recipes/tags/namedtuple/">namedtuple</a>, <a href="/recipes/tags/nodevisitor/">nodevisitor</a>, <a href="/recipes/tags/parsing/">parsing</a>). Revision 14. </p> <p>In some cases it may be desirable to parse the string expression "f1(*args)" and return some of the key features of the represented function-like call. </p> <p>This recipe returns the key features in the form of a namedtuple. </p> <p>e.g. (for the above)</p> <pre class="prettyprint"><code>&gt;&gt;&gt; explain("f1(*args)") [ Call(func='f1', starargs='args') ] </code></pre> <p>The recipe will return a list of such namedtuples for <code>"f1(*args)\nf2(*args)"</code> Note that while the passed string expression must evaluate to valid python syntax, names needn't be declared in current scope.</p>
