Yes, No, Yes.

You can answer such questions yourself very easily, e.g. in this case:

 >>> import calendar
 >>> calendar.month_abbr
<calendar._localized_month instance at 0x00AE84E0>
 >>> list(calendar.month_abbr)
['', 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 
'Oct', 'Nov', 'Dec']
