After a quick check I got:
D:\Works\Python\PP4E-Examples-1.4\Examples\PP4E>py
Python 3.4.4 (v3.4.4:737efcadf5a6, Dec 20 2015, 19:28:18) [MSC v.1600 32
bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> t = ('myname',)
>>> n = (3,)
>>> n + t
(3, 'myname')
>>>
I may overlook Gary's reply. The "any" has not unpacked yet at that
time:-) My fault, sorry.

Yes, (I think) I know the *any usage, but don't know their type will be
changed after unpack?

In fact, the value of *any* is *not* an integer. The *any notation
causes Python to pack all the arguments into a tuple. This feature is
usually used when there are multiple (and an unknown number) of
parameters, but it works perfectly well with a single parameter.
Here's an example:
>>> def progress(*any):
print(any)
>>> progress(1)
(1,)
>>> progress(1,2,3)
(1, 2, 3)
>>>

The attached is a script which can run under Python 3.4/Windows Vista
correctly. One thing make me puzzled is that the "any + context" at line
18. The "any" was passed as an integer from line 43 and the "context"
was defined as a tuple at line 35. This concatenation works! how?
