Yes, it does. That's the way the language is defined to work. If you
don't like it, pick a different language.

No it doesn't. Try it:
Python 2.7.3 (default, Mar 20 2013, 14:16:24)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> name="abcd"
>>> month="efgh"
>>> year="ijkl"
>>>
>>> "k" in (name and month and year)
True
>>> (name and month and year)
'ijkl'
>>>
> how can 'k' contained within 'abcd' ?
It doesn't
