I wonder why 'del' is not a function or method.
Assume,
x = 2.
When a function »f« is called with the argument »x«,
this is written as
f( x )
. The function never gets to see the name »x«, just
its boundee (value) »2«. So, it cannot delete the
name »x«.
Also, the function has no access to the scope of »x«,
and even more so, it cannot make any changes in it.
Therefore, even a call such as
f( 'x' )
will not help much.
What about del team[2]?
There is no name involved here, and even a reference to team[2] won't help.
Presumably there is no other way to do an in-place deletion of an
element of a list. (Inserting an element is different.)
