Deletion is recursively defined, in a very similar way to assignment. Rather than spelling it out in detail, here are some hints.
Deletion of a target list recursively deletes each target, from left to right.
Deletion of a name removes the binding of that name
from the local or global namespace, depending on whether the name
occurs in a
global statement in the same code block. If the
name is unbound, a
NameError exception will be raised.
It is illegal to delete a name from the local namespace if it occurs as a free variable in a nested block.
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).
