6.7 The <tt class="keyword">return</tt> statement

<P>
<tt class="keyword">return</tt> may only occur syntactically nested in a function
definition, not within a nested class definition.

<P>
If an expression list is present, it is evaluated, else <code>None</code>
is substituted.

<P>
<tt class="keyword">return</tt> leaves the current function call with the expression
list (or <code>None</code>) as return value.

<P>
When <tt class="keyword">return</tt> passes control out of a <tt class="keyword">try</tt> statement
with a <tt class="keyword">finally</tt> clause, that <tt class="keyword">finally</tt> clause is executed
before really leaving the function.
<a id='l2h-509' xml:id='l2h-509'></a>
<P>
In a generator function, the <tt class="keyword">return</tt> statement is not allowed
to include an <a class='grammartoken' href="exprlists.html#tok-expression_list">expression_list</a>.  In that context, a bare
<tt class="keyword">return</tt> indicates that the generator is done and will cause
<tt class="exception">StopIteration</tt> to be raised.
