<P>
Deletion is recursively defined very similar to the way assignment is
defined. Rather that spelling it out in full details, here are some
hints.
<a id='l2h-489' xml:id='l2h-489'></a><a id='l2h-490' xml:id='l2h-490'></a>
<P>
Deletion of a target list recursively deletes each target, from left
to right.

<P>
Deletion of a name removes the binding of that name
from the local or global namespace, depending on whether the name
occurs in a <tt class="keyword">global</tt> statement in the same code block.  If the
name is unbound, a <tt class="exception">NameError</tt> exception will be raised.
<a id='l2h-491' xml:id='l2h-491'></a><a id='l2h-492' xml:id='l2h-492'></a>
<P>
It is illegal to delete a name from the local namespace if it occurs
as a free variable<a id='l2h-493' xml:id='l2h-493'></a> in a nested block.

<P>
Deletion of attribute references, subscriptions and slicings
is passed to the primary object involved; deletion of a slicing
is in general equivalent to assignment of an empty slice of the
right type (but even this is determined by the sliced object).
