This one I can understand. But the previous one

which I am still on scratching my head.
Now the question moves from "how" to "why":
Why "del _tmp" at the last step? The only reason I can thought of is
"information hiding", but from whom? A global variable has its reason to be as
a global. It may need to be modified later to influence others behavior. Using
delete to hide the name seems unnecessary and redundant. If someone really
want, he can follow the solution Chris had provided in his reply.

A little strange, but effective:-)
