[catalinfest at gmail.com]

Hi everyone .
My questions is "why vars().has_key('b') is False ?'
I expecting to see "True" because is a variable ...
Thanks
Please see code bellow .
>>> x=11
>>> def something():
...     b=25
...
>>> vars().has_key('x')
True
>>> vars().has_key('b')
False
>>> globals().has_key('x')
True
>>> globals().has_key('b')
False
>>>
