Sorry if this is a stupid question, but what is up with this:

>>> from calendar import*
>>> Calendar

Traceback (most recent call last):
File "<pyshell#9>", line 1, in <module>
Calendar
NameError: name 'Calendar' is not defined
>>> from calendar import Calendar
>>> Calendar
<class 'calendar.Calendar'>

?

Oh, I didn't realise modules could do that. Thanks.

Do you know what the rationale behind not including 'Calendar' is?
